contains a precision reference circuit; a high-resolution, autozeroing, factory-calibrated
A/D converter; and a large (0.52”/13.2mm), easy-to-read, LED display. LED’s are available
in red, yellow and green colors. Red LED’s are also offered in high-intensity or low-power
versions.
long-term operation. Differential input voltage ranges include ±2V, ±20V and ±200V. Input
impedance is a minimum 800kΩ. Non-inverting inputs are overvoltage protected to ±250V,
and CMRR is typically 86dB (dc to 60Hz).
The moisture and vibration-proof package is extremely rugged and well suited for harsh
environments and extended temperatures. Devices are fully specifi ed for
0 to +50°C operation.
power models, whose display is just as bright as standard models, typically consume
175mW. DISPLAY TEST and HOLD functions are standard on each meter, and a complete
set of BCD outputs are optional for sending data to CPU's or remote displays.

A panel-mount retaining clip is supplied with each model. ground for the DMS-40PC internally connected to pin 3 (5V RETURN). Do not connect pin 10 to either pin 3 or your system ground as this will create a ground loop and possibly result in errone- ous readings ...

... Panel Meter Catalog contains an application note describing power sup- ply wiring and ground loop avoidance techniques. The DMS-40PC’s simplifi ed schematic, shown in Figure 1, can be very useful when debugging a malfunctioning circuit, especially if the user has some knowledge of operational amplifi ers (op amps). The meter’s high-impedance input consists amp powered from a ± ...
