CST UNIT  (Custom Units) 

Purpose: 

Sets up a user defined unit display. Can only be used when the Display Menu is set 
for CUST or ROOT. A variety of engineering units can be set.    

Note: These are just display labels and use the menu functions DSP LO, DSP 

HIGH and DEC PNT to control the displayed value. 

Options: 

PA, KPA, MB … CCM, CCH (33 options as listed below)

Press the 

 and 

 buttons to select a number, if no more buttons are pressed the cursor will 

move to the next digit, press the 

 button to enter the number. If a number is entered by mistake 

exit the menu and try again (do not return to the display). 

DP LOW (Differential Pressure Low Output) 

Purpose: 

Alters the differential pressure corresponding to the minimum output level.  

 

The value can be set anywhere within the range of the instrument. The display will 
be in the current engineering units selected. 

Options: 

Any differential pressure value within the display or instrument range.  

DP HIGH (Differential Pressure High Output) 

Purpose: 

Alters the differential pressure corresponding to the maximum output level.  

 

The value can be set anywhere within the range of the instrument. The display will 
be in the current engineering units selected. 

Options: 

Any differential pressure value within the display or instrument range.  

DEC PNT (Decimal Point Position) 

Purpose: 

Alters the position of the display decimal point if the display option is set to CUST or 
ROOT. 

Options: 

NNNN, NNN.N, NN.NN, N.NNN or .NNNN

 

DSP LOW (Display Low Reading) 

Purpose: 

Alters the display value corresponding to the minimum output level. Can be set to 
any numeric value within the range of the display. For instance, to display mA set the 
value to 4.00. For %, set this value to 0. 

Options: 

Any numeric value shown on the display 

DSP HIGH (Display High Reading) 

Purpose: 

Alters the display value that corresponds to the maximum output level. Can be set to 
any numeric value within the range of the display. For instance, to display in mA set 
the value to 20.00. For %, set this value to 100. 

Options: 

Any numeric value shown on the display
