Description

The 800 Plus Universal Digital Meter is a versatile, cost effective solution to a wide variety of monitoring and control applications. The input can be changed by the user to any of the DC voltage and current values listed above by re-locating shorting jumpers on the plug-in signal conditioner card. No calibration equipment is required when changing ranges since they are digitally precalibrated at the factory. Rescaling is accomplished via front panel pushbuttons. Optional alarms and outputs are also front panel programmable.Versatile cost effective solution to a wide variety of monitoring and control applications. No Calibration equipment is required when changing ranges, since they are digitally precalibrated at the factory.
