The DMS-30PC Series is a broad line of self-contained, fully operational, 3½ digit volt-
meters with large, easy-to-read LED displays. The 0.56"(14.2mm) high LED's are available
in a wide variety of colors including red, orange, amber, yellow, green, aqua, blue-green, and
super-blue. A high-intensity version of the red display is optional, as are low-power versions
of the red, orange, and green displays.
The small size (2.17" x 0.92" x 0.56") of DMS-30PC meters is achieved by integrating
their display, display drivers, reference circuit, and A/D converter into in a single, epoxy-
encapsulated assembly. The device's 12-pin, component-like, DIP package is both vibration
and moisture proof. Each package incorporates a built-in color fi lter and bezel and is easily
mounted in either panels or pc cards.
These meters 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 an extremely stable, double-regulated reference and is fully
calibrated prior to potting. We guarantee outstanding initial accuracy (±1 count) and
excellent stability (±0.15 counts/°C). All models operate from a single +5V supply, and the
low-power models draw as little as 10mA (50mW total power). A DISPLAY TEST function is
standard on each device.
For popular applications (4-to-20mA, rms-to-dc conversion, ac line power, J and K ther-
mocouples, etc.), the DMS-30PC Series includes a complete line of optional "plug-on" appli-
cation boards that conveniently convert your meter into an application-specifi c instrument.

    ... The multimeter's negative lead (usually the black one) must be connected to pin 3 (5V RETURN). ments can be made with any DMS-30PC 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 ...

    ... APPLICATIONS 2. Differential Input Confi gurations: Differential measurements can be made with all DMS-30PC meters. 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. ...

    ... The low-power, red LED DMS-30PC-2-RL can be confi gured to allow power supply monitoring over the range of 4.5-18Vdc. The circuit in Figure 8 uses a low-drop-out, three-terminal regulator (LM- 2931Z-5, available from National Semiconductor) to provide regulated 5V power to the meter ...
