Frequently Asked Questions - EX205T Extech
How to measure DC voltage with Extech EX205T?
Turn the rotary switch to the V (DC) position. Connect the black test lead to COM and red to V/Ω/Hz. Touch the probes to the circuit. Read the voltage on the display. If voltage is negative, reverse probes.
How to replace the battery in EX205T?
Turn the meter off and remove the test leads. Unscrew the battery cover screw. Slide off the cover. Replace the 9V battery with a new one (6F22 or NEDA 1604). Reattach the cover and screw.
How to use the continuity test?
Set the rotary switch to the continuity symbol (sound wave). Connect test leads: black to COM, red to V/Ω/Hz. Touch probes to the circuit. A continuous beep indicates continuity (resistance < 30 Ω).
What do the symbols on the display mean?
Common symbols: AC (alternating current), DC (direct current), mV (millivolts), Ω (ohms), kHz (kilohertz), μF (microfarads), hFE (transistor gain), battery icon (low battery), HOLD (data hold active).
How to measure current with EX205T?
For current up to 200mA, use the red lead in the V/Ω/Hz jack; for up to 10A, use the 10A jack. Set rotary switch to the appropriate current range (A or mA). Break the circuit and connect the meter in series. Read the current.
What is the maximum voltage this multimeter can measure?
The EX205T can measure up to 600V DC and 600V AC. Do not exceed this limit to avoid damage or injury.
How to test a diode?
Set the rotary switch to the diode symbol (arrow with bar). Connect red lead to anode, black to cathode. The display shows the forward voltage drop (0.5-0.8V for silicon). Reverse leads should show 'OL' (open).
How to use the data hold function?
Press the HOLD button to freeze the current reading on the display. Press again to release the hold. This is useful for capturing measurements in hard-to-reach places.
What is the auto power-off feature?
The meter automatically turns off after 15 minutes of inactivity to conserve battery. To wake it, rotate the dial or press any button. You can disable this by pressing HOLD while turning on.
How to measure temperature?
Set the rotary switch to the TEMP position. Connect the thermocouple to the meter (red to V/Ω/Hz, black to COM). Touch the probe to the object. The display shows temperature in °C or °F (select with MODE button).
