Introduction Safety Notes The DL250 Digital Clamp-on is the all-in-one test-tool that's designed Before using this meter, read all safety information carefully. In to make quick work of HVAC/R service and industrial maintenance. this manual the word "WARNING" is used to indicate conditions Whether you're measuring flame safeguard current, motor inrush or actions that may pose physical hazards to the user. The word current, run/start capacitors, recording time-stamped temperature "CAUTION"

The maximum limit for this function is 400 amps AC. Too much Measuring Three-Phase AC Volts current will saturate the ferrous material in the clamp, and adversely affect accuracy. WARNING! This meter is primarily designed to measure residential, commercial WARNING! and light industrial AC voltage. When measuring 3-phase circuits, DO NOT attempt to take any unknown voltage or current measure m e n t s line-to-line, the value of the voltage is actually higher than the rated that may be in excess

The voltage or current applied during resistance measurements could Your meter is designed to apply enough voltage, in the forward biased damage some devices. Typically, the voltages applied in the resistance direction, to allow current flow. All diodes use up or “drop” a small ranges vary from 3 volts in the lowest range to 0.5 volts in the highest amount of the supplied voltage when they are forward biased. When range. Current will typically vary from 800 µA at the lowest range to 30 they are

Measuring Capacitance To measure AC or DC current flow (in amps): This meter measures capacitors, such as those used as motor-run-start 1. Ensure power is off to the circuit to be tested. capacitors, ranging in value from .001 to 10,000 microfarads (µf). 2. Insert the test leads into the meter (red to the multifunction port on the right, and black to the common port on the left). WARNING! Capacitors should be completely discharged prior to testing. 3. Set the rotary switch to the DC microamp

Cleaning and Decontamination Fuse Replacement Periodically clean your meter’s case using a damp cloth. DO NOT use The DC µA position is protected by a 400 mA fuse. If this fuse blows the abrasives, cleaning solvents or strong detergents, as they may damage meter will display all zeros (example, 00.00 mA) on the LCD when the the finish or affect the reliability of the structural components.
