ALIBRATION
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?
CAL[n]: XXXX
Where:
[n]
XXXX
+15 C
ALIBRATION
1. Connect the DMM to the +15 volt supply and measure the DMM
2. Issue a CAL[n]:POS15? command. Note the returned value = X.
3. To change the output voltage issue a CAL[n]:POS15 nn
4. Repeat Step 3 until the measured voltage is within the range from
+5 C
ALIBRATION
1. Connect the DMM to the +5 volt supply and measure the DMM
2. Issue a CAL[n]:POS5? command. Note the returned value = X.
3. To change the output voltage issue a CAL[n]:POS5 nn
4. Repeat Step 3 until the measured voltage is within the range from
-5 C
ALIBRATION
1. Connect the DMM to the -5 volt supply and measure the DMM
2. Issue a CAL<n>:NEG5? Command. Note the returned value = X.

Note that a change of one count of nn from the X value returned in
Step 2 will change the output by ≈ 30 mV.
