Allow the supply 30 minutes to warm up and stabilize.
The commands to change the output of the supply are in the form of:
CAL[n]:XXXX? To display the calibration value.
CAL[n]: XXXX nn To adjust the calibration value.
Where:
[n] is the module number.
XXXX is one of the following: POS15, POS5, NEG5, NEG15.
+15 C ALIBRATION
1. Connect the DMM to the +15 volt supply and measure the DMM
voltage. If the voltage is within the range from 14.970 to 15.030
volts the calibration is acceptable so proceed to +5 calibration.
2. Issue a CAL[n]:POS15? command. Note the returned value = X.
3. To change the output voltage issue a CAL[n]:POS15 nn
command.
Note that a change of one count of nn from the X value returned in
Step 2 will change the output by
≈ 30 mV.
4. Repeat Step 3 until the measured voltage is within the range from
14.970 to 15.030 volts.
+5 C ALIBRATION
1. Connect the DMM to the +5 volt supply and measure the DMM
voltage. If the voltage is within the range from 4.997 to 5.003 volts
the calibration is acceptable so proceed to -5 calibration.
2. Issue a CAL[n]:POS5? command. Note the returned value = X.
3. To change the output voltage issue a CAL[n]:POS5 nn
command. Note that a change of one count of nn from the X value
returned in Step 2 will change the output by
≈ 3 mV.
4. Repeat Step 3 until the measured voltage is within the range from
4.997 to 5.003 volts.
-5 C ALIBRATION
1. Connect the DMM to the -5 volt supply and measure the DMM
voltage. If the voltage is within the range from –4.997 to – 5.003
the calibration is acceptable so proceed to -15 calibration.
2. Issue a CAL:NEG5? Command. Note the returned value = X.
