10. Calibration Procedure

All Associated Power Technologies, Inc. instruments have been calibrated at the

factory prior to delivery. The recommended calibration cycle for all APT

instruments is every 12 months.

10.1 Hardware Verification and Calibration Procedure

This instruction sheet covers the hardware calibration procedure for the 300XAC

series power supply. This procedure should be used before standard software

calibration if hardware verification procedure fails. All Tests should be performed

at 60Hz. If the hardware verification does not require adjustment proceed to 10.2

Software Calibration Procedure.

Required Measurement Standard

 DVM capable of measuring millivolts DC and 115VAC, 400VDC

 Oscilloscope

Required Measurement Equipment

 475kΩ, ¼ watt resistor

 11Ω, 1125Watt (minimum) resistor (310XAC)

 5.5Ω, 2250Watt (minimum) resistor (320XAC)

 2.75Ω, 4500Watt (minimum) resistor (340XAC)

 1.8Ω, 6750Watt (minimum) resistor (360XAC)

 10uF, 110V non-polarized capacitor

 Potentiometer adjustment tool

 Inductor adjustment tool

10.2 Activate Non-Calibration Mode

 Press the “0” and “7” keys while simultaneously powering the instrument ON.

10.3 Adjust Control Circuit Power Voltage

1. Connect the DVM to the “+15V” and “G” points on the FLY61000 board

and set to DC volts.

2. Press the “0” and “7” number keys while simultaneously powering the

instrument ON.

3. Adjust the VR1 on the FLY61000 board so that DVM measures “+15V”

volts +/- 0.1V.
