Introduction; Making Measurements; Verify Instrument Operation; Range Selection - Amprobe 34XR-A Mode D'emploi

INTRODUCTION

The 34XR-A is a True rms autoranging handheld digital multimeter for measuring
or testing the following:
• DC and AC voltage
• Temperature
• DC and AC current
• Capacitance
• Resistance
• Diodes
• Frequency
• Continuity
• Dutycycle
Additional features include: MIN MAX, HOLD, Backlight, and Range Lock

MAKING MEASUREMENTS

Verify Instrument Operation

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.

Range Selection

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.
�Warning
To avoid electrical shock while manual ranging use the display
annunciators to identify the actual range selected.
Correcting an Overload (OL or -OL) Indication �
An OL 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 OL indication is normal for some functions; for
example, resistance, continuity, and diode test.
