Adjustment Procedures

Once the process starts, adjust all partial resistors to keep the specified accuracy.
The maximum acceptable deviation of the calibration value to the nominal value of each
resistor is in the Lower Limit and Upper Limit columns. If any of the partial resistors is out of the
shown limits, it must be replaced. Replacement should be done only by an authorized service
center.
High Resistance Source Adjustment 1.5 kV
Fully adjust the low resistance source with the front panel keyboard. Calibration is based on dc
measurements of resistance in the test points in Table 6 . Part of the adjustment sets the test
voltage voltmeter and the adjustment of an external option, Resistance multiplier, respectively.
Use the 8588A and 1653 or similar for these procedures, see
Table 6 .
1. Connect the Product to the 1653 (for values >10 M
Ω
) or to 8588A (for values
≤
10 M
Ω
), see
Figure 21 .
2. Push the Setup softkey on the Product.
3. Select Calibration and confirm with the Select softkey.
4. From the calibration menu, highlight High Resistance Source and push
E
.
