(e) When display returns, taking readings on the 2000 mA range, set
calibrator to STANDBY.
(5) Ac Current
(a) Press mA function pushbutton.
(b) When 100. mA AC is displayed, set calibrator for a 100 mA, 1 kHz
output. Allow approximately 10 seconds for calibrator output stabilization, then press TI
TRIG/STORE pushbutton.
(c) When 1000. mA AC is displayed, set calibrator for a 1.0 A, 1 kHz output.
Allow approximately 10 seconds for calibrator output stabilization, then press TI
TRIG/STORE pushbutton.
(d) When display returns, taking readings on the 2000 mA range, set
calibrator to STANDBY and press RESET pushbutton.
(e) Disconnect calibrator from TI.
(1) Press LOCAL/HF AC pushbutton. When 100.00 mV AC is displayed (also,
a U should appear in the display), connect calibrator to TI INPUT HI and LO terminals.
(2) Set calibrator for a 100 mV, 100 kHz output. Allow approximately 10
seconds for calibrator output stabilization, then press TI TRIG/STORE pushbutton.
NOTE
When TRIG/STORE pushbutton is pressed, the TI display
field blanks while necessary calculations are being performed.
Do not change input voltage while the display is blank.
(3) Repeat technique of (2) above for each successive prompted voltage (at
100 kHz) displayed by the TI. The last prompt should be 200.0 V AC. Afterwards, the TI
will begin taking readings in the 1000 V ac range.
(4) Set calibrator to STANDBY and press RESET pushbutton. Disconnect
calibrator from TI.
(5) Press CAL ENABLE switch to off, using suitable instrument.
(6) Repeat, or perform initially, paragraphs 8 through 13 above.
a. Deenergize and disconnect all equipment
b. Annotate and affix DA label/form in accordance with TB 750-25.
