(1) Connect equipment as shown in figure A-1, connection A.
(2) Remove line power from nullmeter. All measurements should be made using
battery power.
(3) Set DC reference divider MODE switch to 752 CAL and CALIBRATE switch
to+100:1.
(4) Set calibrator output to 0.0 mV, output to OPR.
(5) Short the NULL DETECTOR terminals of the DC voltage divider using a high
quality low thermal short.
(6) Set nullmeter OFFSET to 00,000.00 uV, IMPEDANCE to 10 MΩ, FILT to 2 sec
(or as dictated by measurement stability).
(7) Set nullmeter range to 300 uV (or as desired, see note above).
