Analog Output Tests

Use the display/keypad to test the operation of the analog outputs by

forcing the outputs to known values. Measure then the outputs with a

current/voltage meter.

1. Press any of the arrow buttons to open the Main Menu.

2. Select System and press the right arrow button.

3. Select Diagnostics and press the right arrow button.

4. Select Analog output tests and press the right arrow button.

5. Select one of the testing options Force 0%/50%/100% of scale.

Press the TEST key. All outputs are tested simultaneously. The

actual output value depends on the selected range.

6. Press the OK key to stop testing. Then press the EXIT key to

return to the basic display.

ITEST

Use the serial line to test the operation of the analog outputs. Use the

ITEST command to force the analog outputs to entered values. The set

values remain valid until you enter the command ITEST without

parameters or RESET the transmitter.

ITEST [aa.aaa bb.bbb cc.ccc]<cr>

where

aa.aaa

Current or voltage value to be set for channel 1 (mA or V)

bb.bbb

Current or voltage value to be set for channel 2 (mA or V)

cc.ccc

Current or voltage value to be set for channel 3 (optional)

(mA or V)

Example:

>itest 20 5

Ch1 (Td ) : * 20.000 mA H'672A

Ch2 (T ) : * 5.000 mA H'34F9

>itest

Ch1 (Td ) : -23.204 'C 16.238 mA H'FFFE

Ch2 (T ) : 22.889 'C 8.573 mA H'5950
