e. Connect multimeter terminals to TI RH and X2 terminals.
NOTE
For Leeds and Northrup, model 5300, short GA and X1 terminals
and press B and G switches to obtain indication. This model does
not have an RH terminal.
f. Measure resistance and record indication.
8. Decade Resistors
a. Performance Check
(1) Turn TI 1 ohm decade switch to 1.
(2) Using multimeter measure resistance. (Depress B and G switch on Model 5300 to
obtain indication). Note indication and subtract value recorded in 7 f above. The resultant
value will be between 0.989 and 1.011 ohms.
(3) Repeat technique of (1) and (2) above for decade switch and decade switch positions
listed in table 4. Indications will be within limits specified.
