4. Measure with the meter and input the value on the touch screen in the Enter Measured Value field.
Note that the Product only accepts values in base units. Example: a measurement output is shown
as 12.0000 mV, but the Product expects the value to be input in V.
5. Continue to follow the on-screen instructions OPERATE/Measure/Input Value until all steps in the
function are complete. Alternate meters based on frequency of the step as for 4 a and b.
6. When a section is complete, the Product highlights the following section.
Resistance Calibration Adjustment
The Product begins the adjustment with internal steps.
Once the internal steps complete, the Product prompts for the connection of a DMM configured for
resistance measurements.
1. Connect the meter to the Product for four-wire measurement.
2. Observe the Product calibration adjust value - this drives the required meter range.
3. Set the 8588A as follows: Four Wire Resistance, Range *, NPLC 50, LoI OFF, Guard ON (external
guard).
4. Temporarily set the 8588A as follows: Volts dc. These prevents tripping the calibrator to STBY,
when the calibrator is set to OPERATE.
5. When the Product shows an instruction to set the Product in Operate, push OPERATE.
6. Change the 8588A to the resistance function - all previous setups are preserved.
7. Measure with the meter and input the value on the touch screen in the Enter Measured Value
field
.
8. Continue to follow on-screen instructions for OPERATE/Measure/Input Value until all steps in the
function are complete. Note that the subsequent steps require the meter to be in LoI mode (LoI
ON): 121 k
Ω, 1.21 MΩ.
9. When a section is complete, the Product highlights the following section.
Capacitance Calibration Adjustment
The Product begins the adjustment with a prompt to input the ambient temperature - use the laboratory
temperature at the time of the adjustment.
After the ambient temperature entry, the Product requests an LCR meter connection. Do not connect
the LCR meter to the DUT at this time.
To proceed:
1. Set the LCR meter for Cp Mode, Level 1V, Freq 1 kHz, Speed Slow.
2. Complete ZERO/SHORT compensation of the LCR meter and the lead set for two-wire
measurement when the two-wire setup, including the Y adapter and single banana plugs, is
connected.
3. Do not connect a strap (remove strap) between the Guard and Ground terminals of the DUT for this
function.
4. Connect the LCR meter to the Product for two-wire capacitance measurements.
5. Tap Continue to go to the first adjustment point.
6. For each step, refer to Table 31 for test frequency setup.
