Measuring Resistance

1. Set the Function Switch to
2. If RANGE is displayed, press the RANGE button to enable autoranging.
3. Connect the Test Leads: Red to E, Black to COM
4. Turn off power to the circuit being measured. Never measure resistance across
a voltage source or on a powered circuit.
5. Discharge any capacitors that may influence the reading.
6. Connect the Test Probes across the resistance.
7. Read the display. If o appears on the highest range, the resistance is too large
to be measured.

Measuring Continuity

1. Set the Function Switch to
2. Connect the Test Leads: Red to E, Black to COM
3. Turn off power to the circuit being measured.
4. Discharge any capacitors that may influence the reading.
5. Connect the Test Probes across the resistance.
6. Listen for the tone that indicates continuity (< 35 Ω).
Checking Diodes
1. Set the Function Switch to
2. Connect the Test Leads: Red to E, Black to COM
3. Turn off power to the circuit being measured.
4. Free at least one end of the diode from the circuit.
5. Connect the Test Probes across the diode.
6. Read the display. A good diode has a forward voltage drop of about 0.6 V. An
open or reverse biased diode will read o.

Measuring Capacitance

1. Set the Function Switch to an appropriate µF function and range.
2. Connect the Test Leads: Red to COM, Black to µA mA P(-)
3. Turn off power to the circuit being measured.
4. Discharge the capacitor using a 100 kΩ resistor.
5. Free at least one end of the capacitor from the circuit.
6. Connect the Test Probes across the capacitor. When measuring an electrolytic
capacitor match the test lead polarity to the polarity of the capacitor.
7. Read the display.

Measuring Temperature

1. Set the Function Switch to °C or °F.
2. Connect the K-type thermocouple to a TEMP adapter (XR-TA).
Match the polarity of the adapter to the polarity of the thermocouple.
3. Connect the TEMP adapter to the E and COM inputs.
Note: The 34XR-A is compatible with all K-type thermocouples. The K-type bead
thermocouple supplied with the meter is not intended for contact with liquids or electrical
circuits.
4. Expose the thermocouple to the temperature to be measured.
5. Read the display.
