6 CALIBRATION
This section describes the calibration requirements of the ACX AC Power Source.
6.1 CALIBRATION INTERVAL
The ACX Power Source requires calibration once every six months or after service has been
performed to the system.
6.2 TEST EQUIPMENT REQUIREMENTS
The test equipment listed below is required for calibration of the ACX-Series Power Source.
1. Digital Voltmeter: 4½ Digit True-RMS responding
5000 Hz bandwidth, minimum
2. Frequency counter: 5 digit counter, minimum
3. Digital Ammeter: 3½ Digit True-RMS responding
5000 Hz bandwidth, minimum
(Alternate: Current transformer used in conjunction with the DVM.)
4. Oscilloscope: (Optional but recommended)
5. Load (Resistive): 15 Amps at 150 VAC, 7.5 amps at 300 VAC
6.3 CALIBRATION PROCEDURE
This calibration procedure verifies that system gains for output and metering are set properly and
that the system performance, relative to output power capability is intact. Gains in various signal
paths within the controller are adjusted by the procedure of Paragraph 6.3.1. Output power
capability of the power source is tested by the procedure of Paragraph 6.3.2.
