Analog Output Tests
Use the display/keypad for testing to test the operation of the analog
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
by pressing the ► arrow button.
3.
Select
Diagnostics
by pressing the ► arrow button.

by pressing the ► arrow button.
5.
Select one of the testing options
Force 0%/50%/100% of scale.
Press
TEST
to confirm your selection. All outputs are tested
simultaneously. The actual output value depends on the selected
range.
6.
Press
OK
to stop testing. Press
EXIT
to return to the basic
display.
ITEST
Use the serial line to test the operation of the analog outputs. Use the
command
ITEST
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
]
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)
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
