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 pre-calibrated at the factory. Rescaling is accomplished via front panel push-buttons. 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 pre-calibrated at the factory.
