METER CONFIGURATION

Meter Range Settings

DMR35 meter configuration is controlled through a 5-position dipswitch (SW1-SW5) on the rear of the meter. The individual switches are labelled 1

through 5 on the dipswitch, and the ON position of the switches is also labelled. These switches are used to select both the meter’s measurement

range and the display intensity (brightness).

Switches SW3 through SW5 select the meter’s measurement range, as shown in the table below.

DMR35-DCV1 provides unipolar measurement capability, meaning that

the meter will only measure positive values of input voltage. The bar-

graph will indicate a measurement of zero or less by illuminating the

leftmost LED, and increasingly positive input values will illuminate the

bar-graph to the rightmost LED until all LEDs are illuminated at positive

full-scale. Negative input values will result in an underflow condition of a

flashing zero reading. Positive input values exceeding the maximum

range will result in a flashing overflow condition.

DMR35-DCV2 provides bipolar measuring capability, meaning that it

will measure both positive and negative input voltages. A zero-value

input voltage will illuminate a single center LED. Increasingly negative

input values will illuminate the bar-graph from center to the leftmost LED

until all left-side LEDs are illuminated at negative full-scale, and

increasingly positive input values will illuminate the bar-graph from

center to the rightmost LED until all right-side LEDs are illuminated at

positive full-scale. If the input voltage exceeds the meter’ s currently

selected range, the display will flash to indicate overflow or underflow

conditions.
