Introduction
The CPA1 is a battery-operated capacitance adapter which enables the user to measure various capacitors used in the HVAC/R
industry. This adapter is compatible with most digital multimeters having standard input jack spacing of 3/4 inches and 10 M
Ω
or greater input impedance. The LED near the control switch indicates if this adapter is ON (LED glows) or OFF. This LED also
indicates low battery voltage when it glows dimly.
Features include
• Measurement Range:
40 µF/400 µF
• Operating Temperature:
0˚C to 50˚C (32˚F to 122˚F)
• Output Signal:
0.1 millivolt per 0.01 µF
(40 µF Range)
0.1 millivolt per 0.1 µF
(400 µF Range)
• Battery Type:
9 V, NEDA 1604 or 6F 22
or 006p
• Weight:
138 g (4.87 oz.)
• Size:
104mm x 42mm x 37mm
Note:
Some capacitors are labeled with “M” in place of “µ” to indicate micro as the multiplier.

1. Remove all test leads from the multimeter and set the multimeter to the DC mV range.
2. Plug the adapter into the multimeter’s V (+) and COM (-) terminals, making sure the polarity is correct. When the polarity
is reversed, a minus (-) sign will be appeared in the display.
3. Slide the power switch of the adapter to the desired range.
4. Connect the adapter’s red test lead to the + side and black test lead to the - side of the capacitor under test.
5. Read the capacitance value in the LCD of the multimeter.
