Calibration

Routine calibration is carried out without opening the instrument.
Allow a 10 minute warm-up before commencing calibration.

Equipment Required

A 5.5 digit multimeter with better than 0.02% accuracy on dc volts and better than 0.12%
accuracy on dc current (to 5A); alternatively use a precision shunt for current measurement. An
electronic load set to approximately 2.7A, or a 1.8

15W resistor, for AUX Output calibration.

Calibration

The calibration procedure is essentially the same for both single and triple output models. For
triple models first assign CONTROL to Output 1 and follow the procedure described to calibrate
Output 1; this procedure also includes the calibration of the AUX Output in steps 17 to 22. On
completion, assign CONTROL to Output 2 and calibrate Output 2 (steps 1 to 16 only).
Single models only use steps 1 to 16.

To enter calibration press SHIFT, #, 99. If the instrument is a long way out of calibration, the
default calibration values should be loaded first by pressing SHIFT, #, 91. Pressing ESCAPE at
any time will abort the calibration procedure and revert to the stored calibration values.

Having entered calibration mode, follow the table below. To increment to the next step press OK.
The calibration must be done in sequence. At the end of calibration press OK to store the
calibration. The instrument automatically sets the range and settings at each step.

Use the spin-wheel to adjust calibration; holding down the JOG SET OFF key will give x100
increments to speed up calibration. Pressing SHIFT will show the calibration value.
