1. INTRODUCTION
The DVM810 is a compact multimeter with a 3 1/2 digit LCD for measuring DC and AC
voltages, DC currents, resistance, diodes and transistors (hFE). Full overload protection is
provided. It is an ideal instrument for hobbyists, for use in the field, for laboratories and
workshops and for domestic applications.

FUNCTION AND RANGE SWITCH
This switch is used to select the desired function and range. It also activates the
instrument. Place the switch in the "OFF" position when the instrument is not in use in
order to extend the life of your battery.

DISPLAY
3 1/2 digit display with 7 segments. Height : 0.5" (12.7mm)
3.
"COMMON" JACK
Plug in the connector for the black (-) test lead.
4. "V
P$-$&.
Plug in the connector for the red (+) test lead when you wish to measure voltages,
resistances and currents (with the exception of 10A-measurements).
5. "10A"
JACK
Plug in the connector for the red (+) test lead for all your 10A measurements.
6. TRANSISTOR JACK
Plug in the transistor for hFE-measurements of a NPN or PNP transistor. Use the correct
b.e.c.-connections.
3. SPECIFICATIONS
Maximum accuracy is guaranteed for a one-year period after calibration. Ideal
circumstances require a temperature of 23°C (± 5°C) and a max. relative humidity of 75%.
