(11) Set the 200 (pF)/1000 (pF) switch to 1000 (pF).
(12) Set the CAP SIM (pF) 100’s thumbwheel to 2. Set the 10’s
thumbwheel to “5” (for S/N’s UA and UB); set to 9 (for UC and UE
S/N’s).
(13) Push and hold the PRESS TO READ CAP (pF) pushbutton while
adjusting CAP SIM (pF) control knob to obtain a test set reading of
260.9 pF (for S/N’s UA and UB); 295 pF (for UC and UE S/N’s).
(14) Release the pushbutton.
(15) Rotate the TEST FUNCTION switch to IND AMP.
(16) Verify the indicator reads 1400 lbs. (for UA and UB S/N's) or 1600
lbs. (for UC and UE S/N's).
(17) If the indicator does not show 1400 lbs (for UA & UB S/N’s) or 1600
lbs (for UC and UE S/N’s), adjust the F/FULL located at rear of
indicator.
(18) If the indicator still does give the appropriate reading, replace the
indicator.
Note: AUX calibration is applicable only for 1900C/1900D, UC
and UE. If testing 1900/1900C, UA and UB, skip to step (30).
(19) Rotate the TEST FUNCTION switch to CAP SIM CAL (NORM SYS).
(20) Set the 200 (pF)/1000 (pF) switch to 200 (pF).
(21) Set the CAP SIM (pF) 100’s thumbwheel to “- “. Set the 10’s
thumbwheel to 6.
(22) Push the PRESS TO READ CAP (pF) pushbutton and hold while
adjusting the CAP SIM (pF) control knob to obtain a test set display
reading of 64.1pF.
(23) Release the pushbutton.
(24) Set the MAIN/TOT-AUX/NAC switch to AUX/NAC.
(25) Rotate the TEST FUNCTION switch to IND AMP.
(26) Verify that the indicator reads 0 lbs.
(27) If the reading is not 0 lbs., adjust the indicator using the EMP 2/E 2
switch located at rear of the indicator.
(28) If the indicator still does not read 0, replace the indicator.
(29) Repeat steps (1) thru (28) until an accurate gage adjustment is
obtained.
(30) Set the MAIN/TOT – AUX/NAC switch to MAIN/TOT.
(31) Rotate the TEST FUNCTION switch to CAP SIM CAL (NORM SYS).
(32) Set the 200 (pF)/1000 (pF) switch to 1000 (pF).
(33) Set the CAP SIM (pF) 100’s thumbwheel to 1 for all 1900 models. Set
the 10’s thumbwheel to 7 (UA and UB) or 8 (UC and UE).
