OPERATION, MEASUREMENT TYPE, CAPABILITIES

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

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

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 numerical measurements for

steady-state and slowly changing measurement values.

1

PWRA

Power supply input terminals (100-264 VAC,

50/60Hz)

2

PWRB

3

INA

Current measurement input terminals

4

INB

DIP Switch Settings: Comprised of five individual switches for configuration as

follows:

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 EXAMPLE

In this applcaition, the DMR-ACAx is configured for simple current measurement where a common power and load connection point is shared.
