The calibrator supports the following thermocouple types: B, C, E, J, K, L, N, R, S, T, U, BP, and XK. The characteristics of all the types are described in Specifications section. The calibrator also has a Cold Junction Compensation (CJC) function. Normally this function should be ON and the actual temperature of the thermocouple will be measured. With CJC OFF, the calibrator will measure the difference between the thermocouple at the junction and at its TC input terminal.

Note: CJC off mode should only be used when calibration is being done using an external ice bath.

To use the thermocouple to measure temperature, follow these steps:

1. Attach the thermocouple leads to the TC miniplug, and insert the plug into the input/output of the calibrator, as in Figure 7.

Note: For best accuracy wait 2 to 5 minutes for the temperature between the miniplug and the calibrator to stabilize before any measurements are taken.

2. Switch to lower display from Main Menu.

3. Select TC from the primary parameters. Choose [IN] in the input/output control, and than the thermocouple type from the sensor types. The temperature unit may also be changed from Celsius to Fahrenheit.

The calibrator can also measure the mV of a Thermocouple, which can be used along with a table in case the corresponding TC type is not supported by the calibrator. To do so, proceed as above and choose mV from sensor types.

3.4 Measuring Pressure

Warning!To avoid a violent release of pressure in a pressurized system, shut off the valve and slowly bleed off the pressure before you attach the pressure module to the pressure line.

16

CautionTo avoid mechanically damaging the pressure module, never apply more than 13.5 Nm/10 ftlbs. of torque between the pressure module fittings, or between the fittings an the body of the module.

To avoid damaging the pressure module from overpressure, never apply pressure above the rated maximum printed on the module.

To avoid damaging the pressure module from corrosion, use it only with specified materials. Refer to the pressure module documentation for material compatibility.

To measure pressure, follow these steps:

1. Connect the pressure module to the calibrator as shown in Figure 9.

The calibrator can measure pressure on both the upper and the lower display. This makes it possible to measure pressure in two different units at the same time.

2. Switch to either upper or lower display from the Main Menu.

3. Select [PRESSURE] from the primary parameters.

4. Select the desired measuring unit.

5. Zero the pressure module. The zero function on the calibrator can be found in the pressure zeroing menu.

7. Remote OperationThe calibrator can be remotely controlled using a PC terminal, or by a computer program running the calibrator in an automated system. It uses an RS232 serial port connection for remote operation. With this connection the user can write programs on the PC, with Windows languages like Visual Basic to operate the calibrator, or use a Windows terminal, such as Hyper Terminal, to enter single commands. Typical RS232 remote configurations are shown in Figure 27.

8. Document Mode

8.1 IntroductionDocument mode allows an instrumentation technician to download predefined calibration tests from a PC database for up to 32 work orders. Tests may be defined for switch instruments and analog instruments.

For analog instruments, each test consists of 1 to 21 user selectable test points.

For switch instruments, each test consists of 1 to 5 user defined ramp operations to determine the switch trip and reset points.

For both instrument types, a test may be repeated as many times as necessary to complete the adjustment and calibration of the instrument. Two sets of test results are stored for each work order, an initial As Found set stored during the first test performed, and a final As Left set stored during the last test performed. If only a single test is required to confirm an instrument’s calibration, both sets of test results are the same.

To perform an initial As Found test, the technician selects the work order to be tested from a list on the display. The calibrator cycles through the test

38

points one at a time automatically generating the predefined output values in the case of a calibrator source type, or displaying the predefined values to be set externally for a pressure or manual source type. Once the input has settled, the technician presses a function key to save the actual output and actual input values and step to the next point. Once the last point has been saved, the As Found test automatically ends and the technician is prompted for changes to the work order identification data (any field but work order number can be changed). After that the technician has the option of displaying the As Found test results. Finally, the technician has the option of saving the As Found results into the As Left storage and ending the instrument calibration, of entering an adjustment mode to monitor physical adjustments to the instrument prior to starting an As Left test, or of directly entering the As Left test.

During adjustment mode, the technician can step up and down the list of test points and the calibrator automatically generates the corresponding predefined output value in the case of a calibrator source type, or displays the predefined value to be set externally for a pressure or manual source type. In this way any changes to the predefined test points resulting from physical adjustments to the instrument may be evaluated. The technician can also enter source values different from the test points and monitor the corresponding input values. When the adjustment is complete, a function key is pressed to enter the As Left test.

During the As Left test, the calibrator cycles through the test points one at a time automatically generating the predefined output values in the case of a calibrator source type, or displaying the predefined values to be set externally for a pressure or manual source type. Once the input has settled, the technician presses a function key to save the actual output and actual input values and step to the next point. Once the last point has been saved, the As Left test automatically ends and the technician has the option of displaying the As Left test results. Finally, the technician has the option of ending the instrument calibration, of entering an adjustment mode to monitor physical adjustments to the instrument prior to starting a further As Left test, or of directly entering a further As Left test.

Additional As Left tests may be performed after instrument calibration has ended as long as the original work order has not been erased from storage. A menu item is available for selecting any work order and starting another As Left test.

Review functions are available to view test results on the calibrator display.

Individual or all work orders may be erased from storage using menu functions.

Press the EXIT function key to return to the first level document mode menu without selecting a work order.

8.2.2 Data Collection, Analog Instruments

The test for each point consists of setting the calibrator output to the predefined value, waiting for the input to settle, and saving the data. This

49

process is repeated until all test points are completed. For ease of analysis, it is suggested that the test points be evenly spaced across the test range and that they be entered in ascending order, descending order, ascending followed by descending, or descending followed by ascending.

If the test includes a pressure input or output, the pressure module is validated and zeroed first as described in section 8.2.2.5. After the module has been zeroed, proceed as described below.

The prompt sequence displayed during the test depends on the input and output types selected. Any combination which includes a pulse train calibrator output or a manual calibrator input has its own unique prompt sequence. All other combinations are covered by a generic test prompt sequence.

8.2.2.1 Generic Test Prompt Sequence

A prompt sequence similar to the following is displayed for each test point when the input/output combination does not include a pulse train calibrator output or a manual calibrator input.

8.2.3 Data Collection, Switch Instruments

The full switch test consists of up to five independent ramp tests. Each test has four parameters, a start value, a start settle time, an end value, and a start to end ramp time. For an ascending ramp the end value is greater than the start value. For a descending ramp the end value is less than the start value. Ascending and descending ramps may be mixed in any order.

A single ramp test consists of setting the calibrator output to the start value, waiting for the start settle time to elapse, and ramping the calibrator output to the end value while monitoring the switch for a state change. The test ends when the switch changes state or the end value is reached. If the switch changes state, the calibrator output at that moment is recorded as the trip point. If the switch never changes state, the trip point is recorded as NONE.

The start value, end value, and start to end ramp time determine the size of each output step during the ramp. There are two output steps per second. This gives the switch time to react to each step change in the output. To reduce the output step size, either increase the start to end ramp time or reduce the difference between the start value and the end value.

If the calibrator output is pressure, setting the start value and ramping the pressure must be done manually with an external device. Before the first ramp test, the pressure module is validated and zeroed as described in section 8.2.2.5.
