and COM inputs.

(4) Connect resistance standard to TI V Ω

(5) Set resistance standard and TI to settings and indications listed in first row of

table 6. If TI does not indicate within limits specified in first row of table 6, perform

b below.

(6) Repeat technique of (4) and (5) above, using remaining settings and indications

listed in table 6. If TI does not indicate within limits specified in table 6, perform b below.

13. Frequency, Dwell, and Duty Cycle

a. Performance Check

(1) Connect function generator to TI V Ω

and COM inputs.

(2) Set TI rotary switch to Hz ~. Press TI rotary switch pushbutton for 2 seconds to

put the TI in the ac-coupled frequency function.

(3) Set function generator for an output of 300 mVrms at a frequency of 20.000 kHz.

TI will indicate between 19.98 kHz and 20.02 kHz.

(4) Set TI rotary switch to (Dwell) < %. Manually range TI to 4-cl.

(5) Set function generator as indicated in (a) through (d) below.

(a) Output: 8.00 V p-p.

(b) Dc offset: 4.00 V.

(c) Waveform: Triangle.

(d) Frequency: 100 Hz.

(6) TI will indicate between 4-33 and 4-71. If TI does not indicate within limits

specified, perform b below.
