Remote Readback Zero Calibration; Constant Voltage Full Scale Calibration - Agilent Technologies 6033A Service Manual

Remote Readback Zero Calibration

Note:
This procedure and the following three procedures must be done as a set, without omitting any of the four
procedures. Also, the following four procedures require that V-MON ZERO (A2R22) be adjusted within
specifications. If it is not, perform the Voltage Monitor Zero Calibration before proceeding.
a. Connect an external supply to the power supply as shown in Figure 2-2.
b. Send string "VSET 0; ISET 5; OUT ON''.
c. Attach the DVM from
Adjust A8R40 (CV PROG ZERO) to 625µV ± 30µV.
d.
e. Remove the DVM.
f. Enter and run the following program and begin noting the controller's display:
10 OUTPUT 705; "VOUT''
20 ENTER 705; A
30 DISP A
40 GOTO 10
50 END
g. Adjust A8R51 (READBACK ZERO) until the value displayed on the controller toggles between:
0 and 5mV (6033A).
0 and 15mV (6038A).
h. After adjusting A8R51 you must continue the calibration procedure through to the completion of Constant Voltage
Zero Calibration. Remember to disconnect the external power supply and resistor.

Constant Voltage Full Scale Calibration

Note:
Perform this procedure only after completing Remote Readback Zero Calibration.
a. Remove all external test circuits.
b. Send string:
"VSET 200; ISET 5; OUT ON" (6033A).
"VSET 60; ISET 5; OUT ON" (6038A).
