Frequently Asked Questions - MN26 Extech
How do I measure DC voltage with the Extech MN26?
Turn the dial to the V DC range (200mV to 600V). Insert the black lead into COM and red lead into VΩ. Connect probes to the circuit and read the display.
How do I measure AC voltage?
Turn the dial to the V AC range. Use the same lead connections as DC. The meter displays the RMS value.
How do I measure resistance?
Turn the dial to the Ω range. Insert leads into COM and VΩ. Touch probes to the resistor leads. For best accuracy, disconnect power from the circuit.
How do I test continuity?
Turn the dial to the continuity symbol (diode with sound waves). Connect probes as for resistance. The buzzer sounds if resistance is below 30Ω.
How do I replace the battery?
Turn off the meter. Remove the screw on the back cover. Lift off the cover and replace the 9V battery. Reattach the cover and screw.
What is the accuracy of the MN26?
Accuracy is specified as ±(% of reading + digits). For DC voltage, it is ±0.5%. Refer to the manual for full details.
Can the MN26 measure temperature?
No, the Extech MN26 does not have a temperature measurement function.
How do I use the data hold function?
Press the HOLD button on the side of the meter. The display will lock the current reading. Press again to release.
What is the maximum voltage the MN26 can measure?
The maximum voltage is 600V for both AC and DC. Do not exceed this rating to avoid damage.
How do I test a diode?
Turn the dial to the diode symbol. Connect the black lead to COM and red to VΩ. Place the red probe on the anode and black on the cathode. The display shows the forward voltage drop.
