DVAM-02 (0-99.9v and 0-50A)
Combination Voltmeter and Ammeter
Do you have a requirement to measure DC voltage and current in the Ham Shack, on the test bench, in your motorhome or boat or for monitoring a solar panel array?
The DVAM-02 is a versatile and inexpensive panel meter which can measure DC voltages from 0 to 99.9v and current flow from 0 to 49.9 amps.
The compact panel meter contains dual LED displays. The top display in Red LEDs shows voltage measurements from 0 to 99.9 volts, while the bottom display in Amber shows current measurement from 0 to 49.9 amps.

Connecting The Digital Panel Meter
Connection - Most Common Setup
Connection - Isolated Power Supply
Calibration and Zero Adjustment
Periodic adjustment of the meter is possible. With the meter turned off (power removed), apply a short (jumper) between test points A and B. With the jumper in place, apply power to the meter which will be automatically calibrated to zero. Remove the jumper placed between A and B.
The current display can also be adjusted through the trim pot R7. Simply apply a known current across the meter of approximately 25A (mid-way between the maximum value). Adjust R7 until the meter displays the correct current reading.
