To verify:
1. Connect the 4-pin connectors AUX 1 + (pin 1) to the 8846A INPUT HI.
2. Connect the 4-pin connectors AUX 1 – (pin 2) to the 8846A INPUT LO.
3. Connect the 17xx AUX Adapter box AUX 1 + and AUX 2 + to the calibrator Normal HI 4.
4. Connect the 17xx AUX Adapter box AUX 1 – and AUX 2 – to the calibrator Normal LO.
5. Set the 8588A to DC V.
6. Apply the voltages in
7. Verify that the AUX 1 readings are between the limits.
8. After the values are checked for AUX 1, move the 4-pin connectors leads to AUX 2; Pin 3 to
the 8588A INPUT HI; pin 4 connected to the 8588A INPUT LO.

Calibration Adjust Procedure

This procedure adjusts the Analyzer accuracy at ambient temperature 23 °C ±5 °C (intrinsic
error). The required equipment and cables for calibrating the Product are listed in
USB Communication
To prevent electrical shock, personal injury, or fire:
Do not perform the calibration procedures or calibration verification tests

described in this manual unless you are qualified to do so.
Repairs or service should be performed only by qualified personnel.

The Calibration Tool contains an automated adjust. When used, it:
provides connection instructions

can control the calibrator to apply the required voltage

will query the measurement readings of the DMM

will calculate and store the new calibration factors
