Page 2: Safety Precautions
Introduction The Digi-Sense AC/DC Voltage Tester (Model 20250-59) is versatile and easy to use. The instrument is a must-have on your electrical tool belt. It safely measures AC/DC voltage, polarity direction, and circuit continuity. The instrument also provides rotary field indication and low impedance testing. - Page 3 WARNINGS In order to avoid electrical shock, valid safety regu- lations regarding excessive contact voltages must be followed. These include voltages exceeding 60 VDC and 25 VAC RMS. Prior to measurement, make sure that the test leads and instrument are in working order. When using this instrument only the handles of the probes may be touched –...

Page 6: Setup And Operation
Setup and Operation Measuring Point Lighting The voltage tester has a battery-operated measuring point lamp. Press button (9) to switch this lamp on. The lamp stays on as long as this button is pressed. When the button is released, the lamp goes off. The lighting button is arranged in such a way that it can also be pressed during low impedance measurements. - Page 7 The LCD shows the voltage values numerically and in the form of a bar graph. The type of voltage (alternating cur- rent = AC, direct current = DC) and the polarity are also shown on the LCD. In the event of negative DC voltage, the numeric voltage value is preceded by “-“.
- Page 8 Rotating Field Direction Display The voltage tester can show the direction of the rotating field with three-phase systems. Always hold the voltage tester by the handles designed for this purpose. Never touch the device beyond the handle ends. Hold the two test tips on the measuring points to be tested.
- Page 9 Using Voltage Tester as a Single-Pole Phase Tester The voltage tester can also be used as a single-pole phase tester. Always hold the voltage tester by the handles designed for this purpose. Never touch the device beyond the handle ends. This phase test serves as a quick test only.

Page 12: Maintenance And Repair
Maintenance and Repair Maintenance and Disposal Check the correct operation of the voltage tester regularly. It can be assumed that risk-free operation is no longer possible if: • There is visible evidence that the device has been damaged. • The device has been stored under unfavorable conditions for a long period of time. - Page 13 Battery Replacement The voltage tester is powered by two AAA batteries supplied with the instrument. They are replaced as follows: 1. Loosen the screw on the battery compartment lid (10) with a screwdriver and remove it. 2. Insert two AAA batteries into the compartment observ- ing the correct polarity information in the compartment.
