Introduction

The Digi-Sense 3-in-1 Digital Multimeter (Model 20250-52)
is versatile yet easy to use—a must-have on your electrical
tool belt. This pocket-sized multimeter safely measures
common ranges of voltage, current, and resistance. For
added convenience, it features noncontact voltage probes,
built-in flashlight, and auto-ranging. The instrument is fully
tested and calibrated to NIST-traceable standards. Careful
use of this meter will provide years of reliable service.

Safety Precautions

1. Improper use of this meter can cause damage, shock,
injury or death. Read and understand this user manual
before operating the meter.

2. Make sure any covers or battery doors are
properly closed and secured.

3. Always disconnect the test leads from any voltage
source before replacing the battery or fuses.

4. Do not exceed the maximum rated input limits:

Input Limits

Function Maximum Input
V DC or V AC 600 V DC/AC
µA, mA, AC/DC 200 mA / 500 V fast-acting, resettable fuse

600 V DC/AC
Diode, Continuity
Test

5. Use great care when making measurements if the
voltages are greater than 25 VAC rms or 35 VDC.
These voltages are considered a shock hazard.

6. Always discharge capacitors and remove power from
the device under test before performing Resistance,
Diode, or Continuity tests.

7. Remove the battery from the meter if the meter is to
be stored for long periods.
