(2) Set READ mASEC-ERASE switch to ERASE.
(3) Set mASEC mA switch to mASEC. If TI does not indicate 0000, 1 digit, adjust
R14 ZERO (fig. 2) until TI indicates 0000.
(4) Using cables of equal length connect calibrator output to TI MA and COMMON
inputs and to frequency counter A input.
(5) Set mASEC mA switch to mA.
(6) Set calibrator for an initial 22 mA output and, if necessary, rotate calibrator
knob below EDIT FIELD pushbutton to adjust calibrator for a TI indication of 22 mA.
(7) Set calibrator to STANDBY.
(8) Connect digital multimeter to TI TP3 (fig. 2) and COMMON terminal.
(9) Set mASEC mA switch to mASEC.

(10) Momentarily set calibrator to OPERATE. If digital multimeter does not
indicate less than 1 V dc with +22 mA applied to TI, adjust R7 +COMP (fig. 2) until digital
multimeter indicates less than 1 V dc.
