Introduction
The Digi-Sense Heavy-Duty Autoranging Digital Multimeter with Bluetooth
®
Connectivity (model 20250-64) allows you to transmit data directly to your Android™ or iOS® device using our free D/S Meter 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—ideal for record keeping at large sites.
Setup is simple. Download the free D/S Meter app to your Android or iOS device. Place the multimeter in Bluetooth mode and open the app on your smart device. The meter will be sensed by your device and be listed as an available source that you can select. Once selected, the data sensed by the meter is displayed on your device and some of the instrument functions can be accessed. A full description of its operation is available for download in the app.
The Heavy-Duty Digital Autoranging Multimeter measures AC/DC voltage, AC/DC current, resistance, frequency (electrical & electronic), capacitance, diode test, and continuity. The meter also offers True RMS for more accurate current readings, temperature measurement with a type K thermocouple, and analog bar graph for viewing trends. Rugged IP67-rated waterproof design withstands heavy-duty use. This instrument is fully tested and calibrated to NIST-traceable standards for reliable measurements right out of the box, saving you time and money. Proper use and care will provide many years of reliable service.

situation, which if not avoided, could result in death or serious injury.
CAUTION symbol indicates a potentially hazardous situa­tion, which if not avoided, may result in product damage.
This symbol advises the user that the terminal(s) so
MAX
marked must not be connected to a circuit point at which the voltage with respect to earth ground exceeds (in this case)1000VAC or 1000VDC.
This symbol adjacent to one or more terminals identifies them as being associated with ranges that may, in normal use, be subjected to particularly hazardous voltages. For maximum safety, the meter and its test leads should not be handled when these terminals are energized.
This symbol indicates that a device is protected through­out by double insulation or reinforced insulation.

Safety Instructions
This meter has been designed for safe use but must be operated with caution. The rules listed below must be carefully followed for safe operation.
1. NEVER apply voltage or current to the meter that exceeds the
specified maximum:
Input Protection Limits
Function Maximum Input V DC or V AC 1000 VDC/1000 VAC RMS mA AC/DC 500 mA 1000 V fast acting fuse
A AC/DC
Frequency, Resistance, CAP, Diode Test, Continuity, Temperature, Duty Cycle
Surge Protection: 8 kV peak per IEC 61010
2. USE EXTREME CAUTION when working with high voltages.
3. DO NOT measure voltage if the voltage on the “COM” input
jack exceeds 1000V above earth ground.
4. NEVER connect the meter leads across a voltage source while
the function switch is in the current, resistance, CAP, or diode mode. Doing so can damage the meter.
5. ALWAYS discharge filter capacitors in power supplies and
disconnect the power when making resistance or diode tests.
6. ALWAYS turn off the power and disconnect the test leads
before opening the covers to replace the fuse or batteries.
7. NEVER operate the meter unless the back cover and the battery
and fuse covers are in place and fastened securely.
8. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

Setup and Operation
WARNING: Risk of electrocution. High-voltage circuits, both
AC and DC, are very dangerous and should be measured with great care.
1. ALWAYS turn the rotary function switch to the OFF position when the meter is not in use.
2. If “OL” appears in the display during a measurement, the value exceeds the range you have selected. Change to a higher range.
DC Voltage Measurements
CAUTION: Do not measure DC voltages if a motor on the circuit
is being switched ON or OFF. Large voltage surges may occur that can damage the meter.
1. Set the rotary function switch to the green VDC position.
2. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive V jack.
3. Touch the black test probe tip to the negative side of the circuit and touch the red test probe tip to the positive side of the circuit.
4. Read the voltage in the display.
