SAFETY INFORMATION
Warning
Do not alter the Product and use only as specified, or the
protection supplied by the Product can be compromised.
• The 38XR-A Digital Multimeter is for use with fixed
equipment installations, such as, distribution panels,
feeders and short branch circuits and lighting
systems in large buildings; and for the primary supply
level, such as, an electric meter or an overhead or
underground utility service.
3
• Do not exceed the maximum overload limits per
function (see specifications) nor the limits marked on the
instrument itself. Never apply more than 1000V dc/750 V
ac rms between the test lead and earth ground.
• Inspect the DMM, test leads and accessories before
every use. Do not use any damaged part.
• Never ground yourself when taking measurements. Do
not touch exposed circuit elements or test probe tips.
• Do not operate the instrument in an explosive
atmosphere.
• Exercise extreme caution when: measuring voltage
>20V // current >10mA // AC power line with
inductive loads // AC power line during electrical
storms // current, when the fuse blows in a circuit
with open circuit voltage >1000 V // servicing CRT
equipment.
• Always measure current in series with the load –
NEVER ACROSS a voltage source. Check fuse first.
Never replace a fuse with one of a different rating.
• Remove test leads before opening the Battery Cover
or case.

INTRODUCTION
The 38XR-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
• Temperature
• Capacitance
• Diodes
• Continuity
• dBm
• 4 - 20 mA Loop Current
Additional features include: MIN MAX AVG, HOLD, REL,
PEAK±, Range Lock, RS-232 IR communication, and Backlight.
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 38XR-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 and the range is locked. When
appropriate, 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. If RANGE still shows on the display,
autoranging is not appropriate for the selected function.
Use autorange for all initial measurements. Then, when
appropriate, use the RANGE button to select and lock a range.
