ALIBRATION
The following procedures are for five-point calibration:
STEP DESCRIPTION
1. Issue a *CLS[n] command.
2. Issue a *RST[n] command.
3. Program the overvoltage protection to maximum to prevent nuisance trips:
CAL[n]:OUTP:VOLT:PROT:DAC 65535
4. Program the output current to full scale to prevent Constant-Current
operation:
CAL[n]:OUTP:CURR:DAC 65535
5. Program the output of the first calibration point by sending the following
command string from the computer:
CAL[n]:OUTP:VOLT:DAC 3275
6. Let the output settle and measure the voltage with a high precision voltmeter;
this is value 1.
7. Enter the actual output voltage value of the first calibration point:
CAL[n]:OUTP:VOLT:FIVEPOINT 1
8. Program the output of the second calibration point by sending the following
command string from the computer:
CAL[n]:OUTP:VOLT:DAC 19000
9. Let the output settle and measure the voltage with a high precision voltmeter;
this is value 2.
10. Enter the actual output voltage value of the second calibration point:
CAL[n]:OUTP:VOLT:FIVEPOINT 2
11. Program the output of the third calibration point by sending the following
command string from the computer:
CAL[n]:OUTP:VOLT:DAC 32000
12. Let the output settle and measure the voltage with a high precision voltmeter;
this is value 3.
