short leads in order to avoid introducing any stray inductance.
(d) When using the optioned test leads, remember that the leads introduce a
measurable capacitance to the measurement. As a first approximation, the
test lead capacitance may be measured by opening the leads at the trips,
recording the open circuit value and subtracting that value.
(e) Capacitors, especially electrolytic, often have notoriously wide tolerances.
Do not be surprised if the measured value is greater than the value marked
on the capacitor, unless it is a close tolerance type.However, values are
seldom drastically below the rated value.
(f) If changing range, measured value will be changed; leakage-voltage
capacitors will be checked also. Leakage-resistance will be decreased in
lower range.
6. MAINTENANCE
1) 9-Volt battery replacement
a. Ensure the instrument is not connected to any external circuit. Set the selector
switch to OFF position and remove the test leads from terminals.
b. Remove the screw on the bottom case and lift the bottom case.
c. Remove the spent battery and replace it with a battery of the same type.
2) Fuse replacement
a. Ensure the instrument is not connected to any external circuit. Set the selector
switch to OFF position and remove the test leads from terminals.
b. Remove the screw on the bottom case and lift the bottom case.
c. Replace the fuse with the same type and rating: 5
20mm, 200mA/250V,
fast-blow fuse or as the replacements.
