Model 2303-PJ front panel calibration
Use the following procedure to calibrate the Model 2303-PJ from the front panel. Table 2-3
summarizes the calibration steps.
NOTE
Calibration must be performed in the following sequence, or an error will occur. To
abort calibration and revert to previous calibration constants at any time during the
procedure, press the MENU key.
Step 1: Prepare the Model 2303-PJ for calibration
1. Turn on the Model 2303 and the digital multimeter, and allow them to warm up for at
least one hour before performing calibration.
2. Press the MENU key, then choose CALIBRATE UNIT, and press ENTER. The instru-
ment will display the date last calibrated:
CALIBRATE UNIT
LAST ON 02/01/98
3. Press the up arrow key. The instrument will display the number of times it was
calibrated:
CALIBRATE UNIT
TIMES= 01
4. Press the up arrow key. The unit will then prompt you to run calibration:
CALIBRATE UNIT
RUN
5. Press ENTER. The unit will then prompt for the calibration code:
CALIBRATE UNIT
Cal Code KI002303
6. Using the edit keys, set the display to the current calibration code, then press ENTER.
(Default: KI002303.) The unit will then prompt you as to whether or not to change the
code:
CALIBRATE UNIT
Change Code NO
7. Be sure NO is selected (use the up and down arrow keys), press ENTER, then follow the
steps below to calibrate the unit. (See
Changing the calibration code
at the end of this
section if you wish to change the code.)
Step 2: Perform calibration steps
NOTE The unit will display the most recently calibrated values. Factory defaults are shown
in this manual.
1. Connect both the OUTPUT SOURCE and DVM IN terminals to the digital multimeter,
as shown in Figure 2-2. (Connect SOURCE + and DVM IN + to DMM INPUT HI; con-
nect SOURCE - and DVM IN - to DMM INPUT LO.)
