Precision Process Calibrator 

 

Product Description 

 

 

Function Keys 

 

For all but Thermocouple output modes, toggle between 
Standby and Operate modes. In Standby mode, changes to 
the output value in the display is not applied to the terminals 
until you select the Operate mode. In Operate mode, each 
change to the output value in the display is applied to the 
terminals immediately. Voltages more than 30 V are not 
applied to the terminals and the mode automatically reverts 
to Standby for your safety. 

E

 

Changes the Product output or parameter to the numeric 
value typed into the keypad. 

 

Erases a partial keypad entry and reverts the Product output 
or parameter to its last known value. 

 

Prepares for selection of a secondary function with the 
numeric keypad. The secondary function is shown above 
each numeric key. The display changes to SHIFT ENABLED 
until a numeric key is pushed. To cancel the selection, push 

 

again. 

 Cursor 

Controls 

Push 

M

 or 

 to put the cursor below the digit in an output 

value that is to be increased or decreased.  

Push 

 to increment the digit in the output value where the 

cursor is. 

 

Push 

P

 to decrement the digit in the output value where 

the cursor is. 
 
The 

 and 

P

 keys are also used to adjust LCD Contrast 

level, LCD Backlight level, and Remote Interface 
Configuration selections as given in “LCD and Remote 
Interface Setup Procedure” in Chapter 5 of the Users 
Manual.
