Introduction The DL49 is a hand-held, battery powered, digital meter with clamp-on current measuring capability. This instrument is ideal for anyone that needs to make quick, accurate measurements of voltage, resistance, and AC or DC inductive amperage. Features include • UL listed 3111-1 • Six measurement functions 1. AC inductive amps (to 400 amps) 2. DC inductive amps (to 400 amps) 3. AC Volts 4. DC Volts 5. Ohms 6.
4. Data Hold Push-button: Freezes the value displayed on the digital read-out. LCD Display Functional Description 5. Peak Hold Push-button: Used to capture the highest AC inductive amp reading and to automatically zero (approximately) the inductive DC amp readings. 6. Clamp Lever: Opens and closes current clamp jaw. 7. Rotary Function Switch: Used to power the meter on and off, or to select one of the available measurement functions. NOTE: Measure inductive AC and DC current using the clamp.
Peak Hold When measuring AC amps you can use the PEAK HOLD button on the right side of the instrument to capture the highest measured value. Press and hold until the word PEAK appears along the top of the display and only the highest measured value will be displayed on the LCD. Press and hold a second time or change functions to return to real-time measurement. Measuring Voltage Data Hold The DATA HOLD button freezes the reading displayed on the LCD at the moment it is passed.
For resistance measurements above one megohm the display might take a few seconds to stabilize. This is normal for high resistance readings. NOTE: When servicing the meter, use only the replacement parts specified. Battery: 9V, NEDA 1604 or IEC 6LR 61 Test lead set: ATL55 To measure resistance, follow these steps: 2. Turn off power to the circuit under test and ensure there is no residual voltage present from any source.
