SureTest 164/165 Calibration Procedure Manual

About this manual

The document outlines verification procedures for hot/neutral voltage and neutral/ground voltage. It specifies that a true RMS Digital multi meter with at least 0.5% measurement accuracy is required to measure line voltage or generate a nominal neutral/ground voltage of 7.5 Volts RMS.

The calibration section details the operational steps, including powering on the fixture, setting the output to 120VAC, verifying ground neutral voltage between 7.1VAC and 7.5VAC, and adjusting ACT readings on the Unit Under Test (UUT) using arrow keys to match supply values.

Frequently asked questions

What measurement accuracy is required for the digital multimeter used in this procedure?

The manual requires a true RMS Digital multi meter with at least a measurement accuracy of 0.5%.

What nominal voltage must be generated to verify the neutral/ground connection?

The procedure requires generating a nominal neutral/ground voltage of 7.5 Volts RMS.

What range should the ground neutral voltage reading fall within during calibration?

The reading must be in the range of 7.1VAC to 7.5VAC.
