Frequently Asked Questions - 2117R Uni-T
How do I measure DC voltage with the Uni-T 2117R?
To measure DC voltage, set the rotary switch to the V⎓ range. Connect the red test lead to the VΩmA terminal and the black lead to the COM terminal. Then touch the probes to the circuit. The reading will appear on the display. Select a higher range if the reading is negative or overrange.
How do I measure AC voltage?
Turn the rotary switch to the V~ range. Insert the black lead into the COM jack and the red lead into the VΩmA jack. Connect the probes across the source. The meter will show the true RMS value of the AC voltage.
How do I measure resistance?
Set the switch to the Ω position. Disconnect power from the circuit and discharge all capacitors. Connect the test leads across the resistor. Read the resistance value on the display. For resistances above 1 MΩ, wait for the reading to stabilise.
How do I test continuity?
Set the dial to the continuity test position (usually a diode symbol with sound waves). Connect the test leads to the circuit. If the resistance is lower than about 50 Ω, the buzzer sounds, indicating a closed circuit.
How do I replace the battery?
Ensure the meter is turned off and disconnect the test leads. Remove the screws from the back cover and lift it off. Replace the 9V battery with a new one, observing polarity. Reattach the cover and tighten the screws.
What is the maximum voltage this multimeter can handle?
The Uni-T 2117R has a safety rating of CAT III 600V. Do not exceed 600V between any terminal and ground in category III installations. Higher voltages may cause damage or electric shock.
Does the 2117R have an auto power-off feature?
Yes, the meter automatically powers off after 15 minutes of inactivity. To wake it up, press any button or turn the rotary switch. This helps conserve battery life.
What does the 'R' in 2117R stand for?
The 'R' typically indicates RS232 interface or data logging capability. In some Uni-T models, it denotes a version with remote communication or recording functions. Check the manual for your specific configuration.
How do I use the data hold function?
Press the HOLD button to freeze the current reading on the display. The display will show a hold symbol. Press HOLD again to release the reading. This is useful when reading in dimly lit areas.
What safety precautions should I take when using this multimeter?
Always inspect the test leads for damage before use. Do not measure voltages exceeding 600V. Use the correct terminal and range. Avoid using the meter in explosive atmospheres. Disconnect power before measuring resistance or continuity.
