Introduction
The Digi-Sense AC/DC True RMS Clamp Meter with
Bluetooth
to transmit data directly to your Android
®
Connectivity (model 20250-63) allows you
™
or iOS®
device using our free D/S Meter mobile app. Now
you can view data at a safe distance from potentially
hazardous parameters or even use your smart device
as a real-time secondary display for checking measurements, eliminating the need to write down readings
on paper. The results are automatically stored in the
app with a date-and-time stamp and can be saved as
a CSV file and emailed for future reference, manipulation, or analysis to help determine trends and conditions over a long period of time. You can also use the
app to attach photos and notes to the records creating
a clear reference point for your work.
Setup is simple. Download the free D/S Meter app to
your Android or iOS device. Place the clamp meter in
Bluetooth mode and open the app on your smart
device. The clamp meter will be sensed by your device
and be listed as an available source that you can select.
Once selected, the measured data is displayed on your
device and some of the instrument functions can also be
accessed. A full description of its operation is available
for download in the app.
The AC/DC TRMS Clamp Meter measures AC current
to 1000 A AC, voltage (AC and DC), resistance, capacitance, frequency, temperature, duty cycle, and continuity. Special functions include auto ranging, diode test,
and audible continuity check. This instrument is fully
tested and calibrated to NIST-traceable standards for
reliable measurements right out of the box, saving
you time and money.

SAFETY NOTES
• Do not exceed the maximum allowable input range
of any function:
Function Maximum Input
A AC, A DC 1000 A DC/AC
V DC, V AC 750 V DC/AC
Resistance, Capacitance, Frequency,
Diode Test
Temperature 300 V DC/ AC
• Do not apply voltage to meter when resistance
function is selected.
• Set the rotary function switch OFF when the meter
is not in use.
• Remove the battery if meter is to be stored for longer
than 60 days.

WARNINGS
• Set rotary function switch to the appropriate position
before measuring.
• When measuring volts do not switch to current/
resistance modes.
• Do not measure current on a circuit whose voltage
exceeds 600 V.
• When changing ranges always disconnect the test
leads from the circuit under test.
• Changes or modifications to this unit not expressly
approved by the party responsible for compliance could
void the user's authority to operate the equipment.
Note: This equipment has been tested and found to
comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against
harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there
is no guarantee that interference will not occur in a
particular installation. If this equipment does cause
harmful interference to radio or television reception,
which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and
receiver.

1065DGMAN_20250-63_Rev1.indd 4 07/02/2019 10:31:07 AM
• Connect the equipment into an outlet on a circuit dif-
ferent from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV
technician for help.
CAUTIONS
• Improper use of this meter can cause damage,
shock, injury or death. Read and understand this
user manual before operating the meter.
• Always remove the test leads before replacing the
battery.
• If the test leads need to be replaced, you must use a
new one which should meet EN 61010-031 standard.
• Inspect the condition of the test leads and the meter
itself for any damage before operating the meter.
Repair or replace any damage before use.
• 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.
• Always discharge capacitors and remove power
from the device under test before performing Diode,
Resistance or Continuity tests.
• Voltage checks on electrical outlets can be difficult and
misleading because of the uncertainty of connection to
the recessed electrical contacts. Other means should be
used to ensure that the terminals are not "live".
• If the equipment is used in a manner not specified by
the manufacturer, the protection provided by the
equipment may be impaired.
