Frequently Asked Questions - ACD-15 TRMS-PRO Amprobe
How do I measure AC voltage with the Amprobe ACD-15 TRMS-PRO?
Turn the rotary switch to the V~ position. Connect the black test lead to the COM jack and the red test lead to the V jack. Touch the probes to the circuit and read the display. The meter automatically selects the range.
What does True RMS mean?
True RMS (Root Mean Square) accurately measures non-sinusoidal AC waveforms, such as those from variable frequency drives or distorted power supplies. The ACD-15 TRMS-PRO provides accurate readings regardless of waveform shape.
How do I change the battery?
Turn off the meter and remove the test leads. Unscrew the battery cover screw on the back. Lift the cover, replace the 9V battery (NEDA 1604), reattach the cover, and tighten the screw.
How do I use the continuity test?
Set the rotary switch to the continuity/diode position (usually marked with a diode symbol and a sound wave). Connect the test leads to the circuit. A continuous beep indicates a short circuit (typically < 50 Ω).
What is the maximum voltage I can measure?
The Amprobe ACD-15 TRMS-PRO can measure up to 600 V AC or DC. Do not exceed this rating to avoid damage or injury. The meter is rated CAT III 600 V.
How do I measure resistance?
Turn the rotary switch to the Ω position. Ensure the circuit is de-energized. Connect the test leads across the component. Read the resistance value on the display. For best accuracy, use the REL mode to subtract lead resistance.
Can I measure current without breaking the circuit?
No, the ACD-15 TRMS-PRO is a handheld multimeter that requires connecting the test leads in series with the circuit to measure current. For non-invasive current measurement, you would need a clamp meter.
How do I use the data hold function?
Press the DATA HOLD button to freeze the current reading on the display. Press it again to release the hold. This is useful for capturing readings in hard-to-reach areas.
What is the accuracy of the ACD-15 TRMS-PRO?
Accuracy varies by function. For DC voltage, it is ±(0.5% + 3 digits). For AC voltage (50/60 Hz), it is ±(1.2% + 3 digits). Refer to the manual for full specifications.
How do I clean and maintain the multimeter?
Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Keep the terminals clean and dry. Store the meter in a dry place. Replace the battery when the low battery indicator appears.
