Calibration
Routine calibration is carried out without opening the instrument.
Allow 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.
Calibration
Assign CONTROL to Output 1. 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 anytime 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.
Repeat for Output 2.
