SECTION 5: CALIBRATION
TIMER The timer is run from a precision programmable oscillator and should never require
calibration.
CURRENTMETER The calibration of the currentmeter should be checked on a yearly basis. To do this,
place the MEM/CONT switch in the CONT position. Place the range switch in the 2
AMP range. With nothing connected to the output and the RAISE CURRENT knob in
its fully counter-clockwise position, adjust R10 until the CURRENTMETER reads zero.
With appropriate test equipment (RMS) raise the output current to 80% of each range
and adjust the corresponding calibration potentiometer to agree with your standard.
