Frequently Asked Questions - CM605 MULTIMETRIX

How to measure DC voltage with the CM605?

Set the rotary switch to V (DC voltage). Insert the black lead into the COM terminal and the red lead into the + terminal. Apply the test probes to the circuit. Read the stabilized value. The AUTO icon indicates automatic range selection. A '-' sign indicates reversed polarity.

How to measure AC current with the clamp?

Set the rotary switch to ~A (AC current). Squeeze the trigger to open the clamp and place a single conductor in the center of the clamp. Read the value. Never place both conductors of the same circuit inside the clamp, the reading will be zero.

How to use the Data Hold function?

During measurement, press the HOLD button for 2 seconds. The H icon appears and the measurement is frozen. To disable, press HOLD again for 2 seconds. The H icon disappears.

How to zero adjust for DC current measurement?

Set the rotary switch to A (DC current). Before placing the conductor, press the ZERO button. The △ icon appears and the displayed value becomes the zero reference. Then take the measurement. To exit zero mode, press ZERO again.

What does 'OL' on the display mean?

The OL (Over Load) display indicates a measurement capacity overload. You have exceeded the maximum range of the selected function. For example, in voltage mode, 'OL' appears if the measured voltage exceeds 600 V. Reduce the measured value or change the range if possible.

How to replace the batteries of the CM605?

Disconnect the test leads. Set the rotary switch to OFF. Remove the screw on the battery compartment cover. Replace both batteries with new AAA 1.5 V batteries, respecting polarity. Close the cover and tighten the screw. Remove the batteries if the device is not used for more than 60 days.

How to disable Auto Power Off?

Set the rotary switch to OFF. Hold down the ZERO button while turning the rotary switch to a position other than OFF. The ⓣ icon disappears, Auto Power Off is disabled. To re-enable, set the rotary switch to OFF then to a measurement position; the ⓣ icon reappears.

How to perform a continuity test?

Set the rotary switch to Ω••• (continuity test). Insert the black lead into COM and the red lead into +. Apply the test probes to the two ends of the circuit. If the resistance is less than approximately 100 Ω, a beep sounds, indicating continuity. Ensure the circuit is de-energized.

How to use the Peak Hold function?

Set the rotary switch to a current or voltage measurement position (AC or DC). Press the HOLD button until the P icon appears. Take the measurement. The device displays the maximum peak value and updates automatically. To disable, press HOLD for 2 seconds.

What to do if the device does not turn on?

Check that the rotary switch is not set to OFF. If the batteries are low, the low battery icon appears or the screen stays off. Replace both AAA 1.5 V batteries, respecting polarity. If the problem persists, check that the batteries are making good contact and that the compartment is clean.
