Frequently Asked Questions - UM200 Extech
What is the Extech UM200?
The Extech UM200 is a compact digital multimeter designed for general electrical testing. It measures AC/DC voltage, AC/DC current, resistance, capacitance, and frequency, and includes additional features like a continuity buzzer, diode test, and non-contact voltage detection.
How do I measure voltage with the UM200?
Turn the rotary dial to the voltage setting (V), insert the black lead into the COM jack and the red lead into the V/Ω jack, then connect the test probes to the circuit in parallel. The reading will appear on the display.
How do I measure resistance?
First, ensure the circuit is de-energized. Set the dial to the Ω setting, plug the black lead into COM and the red lead into V/Ω, then touch the probes across the resistor. Read the value on the display.
How do I test continuity?
Set the dial to the continuity/beep symbol (usually a loudspeaker icon). Place the test leads across the connection. If the resistance is low (< about 50 Ω), the meter will produce an audible beep.
How does the Non-Contact Voltage (NCV) detector work?
Move the NCV sensor (located at the top of the meter) close to an AC live wire or outlet. When voltage is present, the meter will emit an audible beep and the LED indicator will flash. This is a safety feature to quickly verify the presence of AC voltage.
How do I replace the battery?
Turn off the meter, remove the battery cover on the back (usually secured by a screw), detach the old 9V battery, connect a new 6F22 battery, and reattach the cover.
What is the maximum voltage the UM200 can handle?
The UM200 can measure voltages up to 600 V AC and 600 V DC. It is safety-rated to CAT II 600 V and CAT III 300 V for transient overvoltage protection.
Does the UM200 have auto-ranging?
Yes, the UM200 features auto-ranging on all measurement functions, simplifying the selection of the correct range. You can also manually select ranges if preferred.
What do the symbols on the display mean?
Common symbols include AC (alternating current), DC (direct current), Ω (ohms for resistance), V (volts), A (amps), µ (micro), m (milli), k (kilo), M (mega), and battery status icon. The display also shows the current measurement unit and function.
Why won't my UM200 turn on?
If the meter does not power on, first check the battery. Replace it if it is low or depleted. Also ensure that the rotary switch is not between two positions. If the problem persists, inspect the battery contacts for corrosion.
