c. Set digital multimeter to 2 V dc range.
a. Performance Check
(1) Connect TI probe terminals to VOLTS/Ω and LOW connectors on digital
multimeter (Types DM 501A and DM 501AOPT02), ensuring RED or positive terminal at
banana plug mates with VOLTS/Ω terminal on digital multimeter. (On Type DM 501,
ensure that RED or positive terminal of banana plug mates with HI terminal on digital
multimeter).
(2) Connect ground-lead clip of TI to OUTPUT LO and PROBE tip to OUTPUT
HI terminal of calibrator.
(3) Set calibrator for 1000 V dc output. If digital multimeter does not indicate
between 0.9600 and 1.0400 V, perform b below.
NOTE
There is no adjustment for Fluke, Model 80K-40 or Tektronix,
Type 010-0277-00.
b. Adjustments
(1) Set calibrator to STANDBY; then press RESET pushbutton.
(2) Remove 4 screws from cover of TI termination box and remove cover.
(3) Set calibrator for a 1000 V dc output. Adjust R1 in TI termination box for a
reading of 1.000 V dc on the digital multimeter (R).
(4) Set calibrator to STANDBY; then press RESET pushbutton.
(5) Replace cover and screws on termination box.
