Note
When you measure a signal that is >1 kHz, lock the HP3458A to the
1 V range. The meter can have 0.05 % to 0.1 % peaking on the
100 mV range.
DC Voltage Calibration
Connect the Product to the HP3458A as shown in Figure 17.

1. Set the Product mainframe in Scope Cal mode, dc voltage section.
2. Set the HP3458A to DCV, AutoRange, NPLC=10, FIXEDZ=on.
3. Push the GO ON softkey.
4. Make sure the HP3458A measurement is 0.0 Vdc + 100 LiV.
5. Push the GO ON softkey.
Note
The Product output goes to standby when the output is more than 33
volts. Push to turn on the output.
6. After the HP3458A measurement becomes stable, type the measurement
into the Product and push .
