Their Autodim circuit automatically adjusts the display’s brightness to suit viewing environments
ranging from total darkness to full, brilliant sunlight. A user-accessible brightness adjustment pin
enables custom intensity settings or display matching in multiple display applications. Washed

reliable LCD display technology. However, in order to remain legible in low ambient light, LCDs
require complex, power-hungry backlighting circuitry. And, these displays typically suffer from
very narrow viewing angles. In contrast, DMS-30DR Series LED-based displays’ power consump-
tion drops as ambient light decreases, and their viewing angle extends to nearly 180 degrees
vertically and horizontally.
darkness—that’s less than 1/10 Watt. At maximum brightness power consumption is typically
less than 200mA (1 Watt). DMS-30DR voltmeters are available in four differential input voltage
ranges: ±200mV, ±2V, ±20V and ±200V. Input impedance is 1,000 megohms for the ±200mV
and ±2V inputs and 1 megohm for the ±20V and ±200V inputs. CMRR for all devices is 86dB,
and inputs are overvoltage protected to ±250V. Each meter incorporates a precision, ultra-stable
voltage reference and is factory calibrated prior to encapsulation.

built-in color fi lter and bezel, and is easily mounted in either panels or pc boards.

... External drivers will see approximately 600Kohms referenced to 5V RETURN. With pin 2 at +0.7Vdc or below, the DMS-30DR’s LED display is off, and total cur- rent drain from a nominal +5V supply is approximately 1mA.

... RETURN). 1. Single-Ended Input Confi gurations: True single-ended measure- ments can be made with any DMS-30DR meter. The circuit of Figure 2 avoids problems normally associated with ground-loop currents. Separate ground runs should be used for 5V RETURN (pin 3) and (–) INPUT LO (pin 12). This will ensure that large LED currents will not fl ...

Figure 3, though not a practical real- world application, uses a voltage divider to demonstrate the concept of a differential input signal. Be careful not to exceed the ±2V common mode voltage limitation for 5V-powered meters. ...
