Initiating Communication

Starting with the UUT off, push and hold Q while turning the UUT on. Continue to
hold Q until "Cal mode" is displayed. The calibration menus, as seen on the PC
screen, are as follows:
725 Calibration Menu
Calibrate Menu
1 - Cal Volts Input
2 - Cal Volts Output
3 - Cal mA Input
4 - Cal mA Output
5 - Cal mV Input
6 - Cal mV Output
7 - Cal Thermocouples
8 - Cal Ohms Hi Source
9 - Cal Ohms Low Source
A - Cal RTD LOW Range
B - Cal RTD HI Range
C - Cal ISO Volts
D - Cal ISO mA
Enter Selection :
To begin calibration, type the cal step (letter or number), then press Enter. You do not
need to run all of the calibration steps when you are in the calibration mode.
When calibrating thermocouples, you must first calibrate mV Input and mV Output. At
the end of each step on the calibration menu, the new calibration constants for that step
are saved, but not actually used until power is recycled.
When calibrating a measurement function, you must enter an input signal. When the
signal is connected and stable, press the space bar to start the adjustment. Usually, the
UUT will display a calibration constant, then prompt for a second input value. Apply the
new input value, then press the space bar. After the adjustment is complete, press the
space bar to return to the Calibration Menu.
When calibrating a source function, you must enter the value of a reading. Type in the
numerical value of the calibration desired. This will put you into the desired calibration
mode. When entering the calibration data for any source mode calibration, be sure that
you enter the value in the units listed, but don't enter the units (mV, mA, etc.). After the
adjustment is complete, press the space bar to return to Calibration Menu. The
calibration values will vary slightly, unit to unit. The constants used in this procedure
may not appear exactly the same as on your UUT, but they should be approximately the
same.
