What this multimeter measures

The aFe Power 4000-count TRMS digital multimeter handles DC and AC voltage, current, resistance, capacitance, frequency, temperature, diodes, continuity and duty cycle. Auto-ranging and true RMS technology give accurate readings on non-sinusoidal waveforms such as inverter outputs. It is built for home DIYers and professionals who need one tool for electrical, appliance and automotive circuit testing.

Safety rating and power

The housing meets CAT II 600V and IP20 protection for use in higher-voltage environments. The unit runs on battery power and includes a 15-minute auto shut-off to preserve cell life. Over-range indication, automatic negative polarity display and data hold add confidence during live measurements.

Display resolution decides suitability

A 4000-count backlit LCD shows the maximum resolution this meter can resolve. If your work demands higher count resolution or additional measurement functions not listed here, this model will not meet that need.

Questions about this item

How do I install the battery and test leads, and what step do people skip?

Insert the 9 V battery into the rear compartment and plug the red lead into the VΩ port and the black lead into COM; many users forget to seat the leads fully until they click.

What maintenance will this multimeter need later?

Replace the 9 V battery when the low-battery symbol appears and inspect the test-lead insulation for cracks; the CAT II 600 V rating remains valid only with undamaged leads.

What limit appears first during sustained use?

The 15-minute auto shut-off activates after inactivity, and the 4000-count display will show OL if voltage exceeds 600 V AC/DC or current exceeds the fused range.
