(18) Adjust signal generator amplitude for a .3 V ac indication on TI. Measuring
receiver will indicate within 1 dB.
(19) Repeat (16) through (18) above at 90, 150 and 250 MHz.
(20) Repeat technique of (16) through (18) above at 350, 550 and 700 MHz.
Measuring receiver will indicate within 3 dB.
b. Adjustments. No adjustments can be made.
a. Performance Check
(1) Set SELECTOR switch to OHMS.
(2) Adjust OHMS ADJ for ∞ meter indication.
(3) Short OHMS and COMMON leads together and adjust ZERO ADJ for 0
meter indication.
(4) Separate OHMS and COMMON leads.
(5) Repeat (2) through (4) above until no further adjustment is necessary.
(6) Connect OHMS and COMMON leads to resistance standard No. 1.
(7) Set resistance standard for a 10Ω indication on TI. If resistance standard
setting is not between 9 and 11Ω, perform b below.
(8) Disconnect TI from resistance standard.
(9) Repeat technique of (2) through (8) above using settings and indications in
table 5. Resistance standard settings will be within limits
specified in
table 5.
