2. Basic principles of operation

2.1. Connection of ultrasonic transducers Normal and angle probes (generally, single element transducers) should be connected always to

the BNC IN connector (IN 1 for two channel version). Dual element transducers shall be connected to BNC IN and OUT connectors (IN 1 and OUT 1 for two channel version). These connectors shall be used also for separate transducers in through-transmission mode.

2.2. Switching ON Press the ON key to switch the instrument ON. will appear on the

display. Then press any arrow (cursor) key to continue. The instrument is ready and PARAM menu is displayed.

2.3. Switching OFF Press the OFF key to switch the instrument OFF from within any mode.

2.4. Main menu

While the instrument is switched OFF, press simultaneously and ON keys. Main menu will

appear on the display. Use and keys to move the cursor and or key to select the appropriate item (command).

Since these functions are not needed for routine operation of the flaw detector, their description

is given in the section Special functions. The use of particular items should be avoided if operator is not sure or does not have appropriate skills. Otherwise, data on the memory chip may be lost and/or principal changes of internal parameters of the instrument might occur!

2.5. Power supply and accumulator charging NiMH (LiIon optional) accumulator is used for power supply. Before charging, it is

recommended to fully discharge the accumulator at least once a week. Charger supplied with the instrument should be used. Charging time of fully discharged NiMH accumulator is approx. 16 hours.

A battery symbol in the bottom right corner of the display indicates a capacity (voltage) of the accumulator. When the voltage has been decreased below the preset level, the battery symbol starts blinking, with audible signal.

Information about the accumulator voltage in Volts is available in the operation menu TOOLS MISC. The voltage value should be within 11 V to 13.9 V for proper operation.

The instrument may be normally used during the charging cycle.



2.6. Memory chip Internal memory chip (capacity 1 MB) allows saving 100 setups, 100 AVG (DGS) and 100 DAC

curves, 780 echographs of A-scans and 100 B-scans, including 10 minutes of voice records. All data and setups may be saved to a PC (using standard delivered software and connecting cable) and load from PC.

2.7. Maintenance DIO562 does not require any special maintenance, except timely charging the accumulator.

2.8. Operation of the flaw detector There is an operation menu with sub-menu for routine operation of the flaw detector next to

the right edge of the display. Use and keys to move the cursor within the appropriate menu. Selected item or its value is always highlighted by blinking cursor and inverse display. Use or key to change the value of the item (function), to switch function On and OFF or move to the next menu or operation sub-menu see DIO 562 Menu.

In order to switch to the next operation menu, use or key when the cursor is on the first (upper) position (name) of the operation menu.

Keys F1 to F5 (so called function keys) are user programmable to individual need of the operator.

2.9. Programming of the function keys F1 F5 The programmable keys F1 F5 have two functions. Short keystroke moves the cursor on the

preprogrammed menu item (within any operation menu or sub-menu). Long press (longer than approx 3 seconds) recalls the instrument setup (i.e. saved settings of the instrument parameters).

Programming of function keys for selected menu items is very simple. If the function key had not been assigned yet, simply position the cursor on the selected item and then press the desired function key. Single acoustic signal sounds as soon as the function key has been pressed and double tone sounds after the key release. The cursor will remain on the selected item. If a single tone sounds after the key release and the cursor moves to another item, then this key had been already assigned. Deleting of the function key assignments is described in the chapter Sub-menu MEMORY. Setting (assignment) of the function keys is saved to the instruments memory with saved setups.

The second function of F1 F5 keys serves for recall of the saved settings (setup). This function cannot be changed. In order to recall the setup from the memory, press the function key for longer than approx. 3 seconds (until the sound signal). Press two function keys simultaneously for numbers 6 to 9 as follows:

F Key F1 F2 F3 F4 F5 F1+F2 F1+F3 F1+F4 F1+F5

Setup number within group 1 2 3 4 5 6 7 8 9

This allows the direct access to the nine setups within a group. The group means choice from ten

setups (1-9, 11-19, 21-29 91-99). The desired group of setups shall be set in the TOOLS SETUP sub-menu. For example, if the memory number #35 had been set, then setup number 31 will be recalled by pressing F1 key (not setup number 1) see section Sub-menu SETUP.



3. Brief description of instrument functions by menu

3.1. Operation Menu DIO 562 offers 4 operation menus (PARAM, GATES, MEMO, TOOLS). When the instrument

had been switched ON, the PARAM menu is displayed as the first.
