OPERATION
3.1 Measuring capacitance
WARNING : 1. Never apply voltage to the test terminals; this could damage or destroy the tester.
2. Fully discharge capacitors before testing them.
3. With polarised capacitors, make sure they are connected with the correct polarity.
4. Do not test capacitors in-circuit.
Procedure:
1. Switch on tester (move on/off switch to "ON" position). The appearance of numbers on the LCD display
indicates the tester is on.
2. Set to the 200pF range. Adjust the zero adjuster so that the lowest digit on the display is as close as possible to
changing from "1" to "0" and the "-" sign does not appear. If you need to use test leads, plug them in before you
zero the tester. Zeroing the tester with the leads connected allows the capacitance of the leads to be nulled.
Do not short the leads together.
3. You should zero the meter whenever you are going to make measurements in order that the last digit will be as
close as possible to "0". We would remind you that the highest resolution available is on the 200pF range.
