20. Resistance
a. Performance Check
pushbutton and .2 range pushbutton.
(1) Press K
(2) Connect resistance standard between TI COM and MA/K
terminals.
(3) Adjust resistance standard to obtain an indication of 199.9 on TI. If decade
resistance standard does not indicate between 198.9 and 200.9 ohms, perform b below.
(4) Repeat technique of (3) above using settings and indications listed in table 11.
If decade resistance standard does not indicate within limits perform corresponding
adjustments listed in table 11.
