Programming the Min Torque
What's Inside
This chapter contains a description of the Min Torque and a
button-by-button procedure for programming the Min
torque.
Min Torque Description
The Min Torque is a value of torque that must be reached
during a test in order for the system to consider the torque
reading valid.
This feature is provided as a method of preventing the
system from recording an erroneous torque during a removal
torque test.
Erroneous torques can be generated from slippage in the
tooling due to the mechanical tolerances of the test sample
and from improper use of the Torqo.
This value is programmed as a percent of the full-scale
torque of the system.
The default value for min torque is 10% of full-scale torque.
10% was selected as a reasonable value because most
measuring devices should not be used consistently in the
bottom 10% of their range. However the torqo, unlike
analog systems, does not lose its accuracy at the low end of
its range and therefore with proper attention to the cap and
bottle tooling measurements can be made below 10%.

During the testing process, the Torqo looks for a torque that
is greater than the Min Torque.
The system will drive 180° in search of this value.
If a value greater than Min Torque is not found then the
error message E 3 will be displayed.
Inputting a Min Torque
The Min Torque can be changed by the following procedure.
Press [Mode] then [Min-TQ]
The current status of this feature will now be indicated on
the display. The default value is 010.0.

Gold Bottle Calibration Check
What's Inside
This chapter describes the Gold Bottle and the procedure for
using it to verify the calibration of the Torqo.
Gold Bottle Description
The Model 1612 Gold Bottle is used to quickly verify the
calibration and operational repeatability of the Model 1502
series torqo's. This bottle is pre-set at the factory to a
customer specified torque value.
Each Gold Bottle is labeled with its exact torque rating.
Since the cap torque of this bottle is the torque produced by
a permanent magnet assembly, the value will always be the
same. Therefore when tested on the Torqo, the measured
value should always repeat unless something has been
damaged.
The bottle is normally supplied with the customers cap so
that the customers Torqo Cap Chuck can be used in the
testing process.
These Gold Bottles are readily available and their torque can
be certified on an annual basis.

Using the Gold Bottle
The Gold Bottle must be tested in the Removal Mode and
since the cap cannot be removed, it therefore cannot be re-
applied.
The following procedure must be used when testing it.
Press [Mode] repeatedly until the Removal LED indicator is
blinking and then press [Next] to terminate the selection
process.
Press [Set-TQ] and key in the value 00.50 and then press
[Next] to terminate the input process.
Insert the Gold Bottle into the bottle holding tooling.
Press [Clear] to zero the display.
Now engage the Cap Chuck.
Press [Open]
Observe the Removal Torque when the Metric LED
indicator is flashing.
The torque reading on the display should now match the
reading on Gold Bottle Label.
The allowable variation is computed by adding together the tolerance on the bottle and the +/- .5% FS tolerance of the machine.
For example:
If the Gold Bottle has a Torque Setting of 12.00 +/- .2 in-lbs
and the Torqo is a 30 in-lb machine then the allowable
variation is +/- .35 in-lbs. (i.e. .2 +.15 = .35)

Performing a User Calibration
Once again the calibration fixture and beam must be
installed on the Torqo before the calibration procedure can
begin.
Calibration Methodology
The calibration procedure consists of entering on the display
a known value of torque that will be applied by the weight
and beam. Then applying this value by hanging the weight
on the calibration cable. At this time the software will
compute the difference between the entered value and the
value applied by the weight. This difference will become the
correction value for this specific point and will be stored in
memory. Once all the points ( i.e. 25%, 50%, 75% and
100% in both the clockwise and counter-clockwise
direction) have been measured the software will compute a
correction curve to be applied during the measuring process.
Entering the Calibration Mode
The Calibration Mode is entered by first turning the
instrument off and then re-powering the system with the
[Cal] key depressed
The front panel will now appear as pictured.
The word HELP indicates that the system is in the calibrate
mode and ready for user input.

Multi-Speed Option
What's Inside
This chapter describes the use of the Multi-Speed Option.
Multi-Speed Option Description
The multi-speed option adds a selector switch on the rear
panel of drive tower.
This option was designed specifically for testing bottle caps
with tamper evident bands. The increased speed of the drive
provides for a cleaner tear of the material that connects the
band to the cap.
This option may also be used for performing more rapid
testing. However one must be careful, when using the
system in this manner, to make sure that the increased speed
is not distorting the measurements.
The Speed Selector Switch enables the user to select the
following four speeds.
Position 1: 1 RPM
Position 2: 2 RPM
Position 3: 4 RPM
Position 4: 6 RPM

When a speed other than 1 RPM is selected, it will be used
in all the Test Modes with the exception of the Removal &
Incremental Mode.
The Removal & Incremental Mode is an industry standard
and cannot be changed.
This test is always performed at 1 RPM
When a high speed is selected, the system will drive at the
selected speed for the first 75% of a closing cycle and then
automatically revert to 1 RPM for the remaining 25%.
Using the Multi-Speed Option
To use this option the operator just has to put the Speed
Selector in the desired position and test in the normal
manner.
As mentioned previously, performing Removal tests at
speeds greater than 1 RPM may distort the data.
To insure the accuracy of the measurements, one should first
perform the tests at 1 RPM and then repeat the tests at a
greater RPM. The results should then be compared for
accuracy and repeatability.

Erratic System Behavior
The Torqo relies on a battery backed memory chip to store
program settings, date and time settings and test results. If
your system has lost the ability to maintain its settings, the
battery in the memory chip may have degraded. This will
result in Erratic System Behavior.
The life expectancy of this device is from 5 to 10 years.
However its life is affected by the amount of time that the
system is turned off because this is when the battery is in
use.
It is not a good idea to stock these devices as backup because their life is measured from date of manufacture.
L's on the Display
When the memory chip has degraded, the Torque readout
will frequently display the letter L in one or more digit
locations.
Checking the Memory Chip
The memory chip can be checked by setting the Date and
Time and then turning the system Off for 30 minutes. If
the battery backup is working the system date and time will
be correct.
A new memory chip can be purchased from Mesa and it
will be supplied with detailed instructions for installing it.

Checking the Drive Belt
A broken drive belt can be detected by attempting to rotate
the drive shaft by hand.
If the Torqo is a standard Model 1502 without the Multi-
Speed option the shaft should not turn more than a few
degrees when rotated by hand.
If the Torqo has the multi-speed option, the shaft will turn
but with a great deal of resistance.
The drive belt is broken when the shaft turns freely in either of the two cases described above.
Replacing the Belt
1. Unscrew the Drive Shaft Knob.
2. Remove the Cover Screws.
3. Remove the Cover by lifting it up and over the
drive shaft.
The drive belt system in this picture is a multi-speed unit
however the procedure for removing a belt, determining the
size of a belt and installing a new belt is basically the same
in all units.
1. To remove the belt, loosen the screws on the motor
plate to take the tension off the belt and then
remove the belt.
2. To install the belt, place it around the sprockets,
slide the motor plate to tension the belt and then
tighten the motor plate screws.

is to lay the broken belt on a flat service and count the
number of drive pins.
Then contact the factory for the correct part number.
Checking the DC Power
1. Put the AC Drive Power Switch in the Off
position.
2. Remove the 12 screws that hold the rear panel on
the tower.
3. Carefully tilt the top of rear panel out as shown in
the picture.
4. Now put the AC Drive Power Switch in the On
position.
5. Observe LED01: It should be on whenever the
tower is energized. This indicates that the +5 vdc
supply is on.
Checking for the Clock Pulses
The clock pulses come from the control instrument to the
drive tower whenever the drive motor is turned on.
With the tower energized, press [Open] and observe the
LED02.
LED02 will be fully on when the motor is not running and
