Introduction

The 34XR-A is a True rms autoranging handheld digital multimeter for measuring

or testing the following:

• DC and AC voltage

• DC and AC current

• Resistance

• Frequency

• Dutycycle

Additional features include: MIN MAX, HOLD, Backlight, and Range Lock

Before attempting to make a measurement, verify that the instrument is operational

and the battery is good. If the instrument is not operational, have it repaired before

attempting to make a measurement.

In addition to autoranging the 34XR-A allows you to manually select and lock a

range by pressing the RANGE button. RANGE appears on the display to indicate

that manual ranging is active. Each subsequent press of the range button steps the

meter to the next higher range. When the highest range is reached the next press

returns the meter to the lowest range. To return to autoranging press and hold the

RANGE button for 2 seconds. RANGE no longer shows on the display.

Use autorange for all initial measurements. Then, when appropriate, use the RANGE

button to select and lock a range.

To avoid electrical shock while manual ranging use the display

annunciators to identify the actual range selected.

Correcting an Overload (oor -o ) Indication W

An o indication may appear on the display to indicate that an overload condition

exists. For voltage and current measurements, an overload should be immediately

corrected by selecting a higher range. If the highest range setting does not

eliminate the overload, interrupt the measurement until the problem is identified

and eliminated. The o indication is normal for some functions; for example,

resistance, continuity, and diode test.

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. Connect the Test Probes to the circuit test points.

5. Read the display, and, if necessary, correct any overload (o) conditions.
