Figure 2. Model 8000A/MAS - top view.
(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.
(11) Set mASEC mA switch to mA.
(12) Set calibrator for an initial 17 mA output and, if necessary, rotate calibrator
knob below EDIT FIELD pushbutton to adjust calibrator for a TI indication of 17 mA.
(13) Set calibrator to STANDBY and set mASEC mA switch to mASEC.
(14) Momentarily set calibrator to OPERATE. If digital multimeter does not
indicate between -13 and -17 V dc, adjust R7 +COMP (fig. 2) until digital multimeter does
indicate between -13 and -17 V dc.
(15) Set calibrator to STANDBY, reverse leads on calibrator and repeat (5) through
(14) above. If digital multimeter does not indicate less than 1 V dc when -22 mA is
applied and between -13 and -17 V dc when -17 mA is applied to TI, adjust R6 -COMP
(fig. 2) until both indications are obtained.
