(2) Set TI range to the 20 V range and set calibrator output for setting for 6 V. TI will
indicate within the limits in table 3 for the 20 V range.
(3) Repeat step (2) above for the 14 V calibrator output. TI will indicate within the
limits for the 14V output.
(4) Repeat step (2) above for the 19 V calibrator output. TI will indicate within the
limits for the 19 V output. Reverse the calibrator leads for negative 19 V. TI will indicate
within the limits for the negative 19 V output. Return the leads.
(5) Set TI range to the 200 V range and set calibrator output for setting for 190 V. TI
will indicate within the limits for the 200 V range.
(6) Set TI range to the 1000 V range and set calibrator output for setting for 950 V. TI
will indicate within the limits for the 1000 V range.
(7) Set calibrator output to minimum.

2000 mV.
(1) Set TI function switch to AC volts
(2) Set calibrator for an output of 1.9 V ac at a frequency of 60 Hz. TI will indicate
within limits specified in table 4 for the 2000 mV range.
(3) Repeat technique of (2) above for the 200 and 750 volt ranges. TI will indicate
within limits specified in table 4 for those ranges.
(4) Set calibrator output to minimum.
