OPERATION, MEASUREMENT TYPE, CAPABILITIES

The DMR35 series meters employ precision, low power electronics to provide high performance full-scale measure of AC voltage. The following

illustrations describe the features and operation to simplify deployment in a wide variety of systems.

FRONT PANEL & FRONT PANEL LAYOUT AND FUNCTION

Bar-graph Display: The 21-segment bar-graph display responds quickly and smoothly like an

analog meter movement to aid in reading rapidly changing measurements.

Numeric Display: The 3-1/2 digit display provides precise measurements for steady-state and

slowly changing measurement values.

DIP Switch: comprised of five individual switches to configure display intensity (SW1-SW2),

measurement mode (SW3), and measurement range (SW4-SW5)

Notes:

1) Ensure all screw-terminals are tightened in accordance with the torque specifications

for reliable operation.

2) Stranded wire is recommended for high-vibration applications.

3) Basic safety isolation is provided between the meter’s measurement and input power

electronics, no connection from the measurement-point and AC input power is required

4) External fusing for input power and or measurement source may be required. It is

incumbent upon the end-user to ensure all local electrical safety regulations and

external fusing requirements are followed where-ever this meter is deployed

CONNECTION EXAMPLES

In this application, the meter is configured for simple voltage

measurement where the meter shares a common load and power

connection point.

In this application, the meter is monitoring a voltage independent of the

meter’s power supply circuit. In such applications, the user must ensure

the voltage between the power and measurement terminals does not

exceed the meter’s isolation voltage rating.
