The 800Plus 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, AC voltage and current, RTD and Thermocouple, Process and Frequency 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 pushbuttons. Optional alarms and outputs are also front panel programmable.

Menu Key
The menu key steps through the various meter parameters that may be selected. These menu items may be “locked out" from front panel selection by software and hardware.

Peak Display Key (Digit Select)
In the Operating Mode, pressing the Peak Display Key causes the peak value of the input signal to be displayed. Pressing the key again returns the display to the present value. In Menu Mode ,the Digit Select Key (Peak Display Key) is used to select input type and decimal point or to select one of the five display digits for programming. In the main menu, pressing the Digit Select Key causes the value or code that is stored for that menu item to be displayed and the left hand digit flashes. Each time the key is pressed, the next digit to the right will flash. The value of the flashing digit may be changed using the Value Select Key. In the Alarm Mode, pressing the Digit Select Key causes the most significant digit of the displayed set point value to flash. Digits are then selected the same as in the Menu Mode.

Reset Key (Value Select)
In the Operating Mode, holding the Reset Key depressed and pressing any other key causes are set to occur. The Menu Key resets all meter functions, the Alarm Key resets any alarm conditions and the Peak Display Key resets the peak value to present value. In the Menu Mode or Alarm Mode, the Value Select Key (Reset Key) sets the value of the flashing digit. Each time the key is pressed, the value increases by one. Holding the key down causes the digit to automatically step through the numbers.

Alarm Key (Reverse Menu)
In the Operating Mode, pressing the Alarm Key displays the set-point of Alarm 1 and then Alarm2. These values may be changed using the Digit Select Key and the Value Select Key. In the Menu Mode, pressing the Alarm Key steps the display backward through the menu.
