Example #2: Use of the LOW SCALE Parameter 

Setup for a 4-20ma transducer signal corresponding to 500-2000 degrees Fahrenheit temperature i.e. 500 degrees at 4ma 
and 2000 degrees at 20ma (one degree resolution): 
 
   DECIMAL 

POINT 

 = 

9999 

   HIGH 

SCALE 

  = 

2000 

   LOW 

SCALE 

  = 

500 

   OFFSET   = 

4.00 

   TARE 

   = 

0.000 

 

Example #3: Use of the TARE Parameter 

Setup for a 0-5Vdc transducer signal corresponding to 0-10.00 pounds of material being packaged in a box weighing 0.50 
pounds with display reading in 0.01 lb. increments.  DSP3200 should display the weight of  the material only (not the box 
as well): 
 
   DECIMAL 

POINT 

 = 

99.99 

   HIGH 

SCALE 

  = 

10.00 

   LOW 

SCALE 

  = 

00.00 

   OFFSET   = 

0.00 

 

 

 

TARE   

 

 

= 0.50 

 
 

SYSTEM CONFIGURATION 

 
After entering the correct pass-code and selecting the blinking 

'SYS'

 (ref. SETUP section), DPS3000 Series goes into 

SYSTEM CONFIGURATION mode.  This mode allows setting up parameters that affect all the channels or the 
instrument in general. 

 

Setup For Display Options 

 
After pushing 

SETUP

 key while 

SYS

 is blinking, the display briefly shows 

'dSP  OPt' 

 (for display option) and then the present Display Option setting.  

Table 3 below lists all 6 display options available. Use 

^v

 key to step thru the 

options. Once the desired Display Option is shown, push 

SETUP

 key to enter 

the setting and go to Setup For Display Time. 

 

Table 3.  Display Options 

  
 
 

 

 

DISPLAY OPTION

 

 

 

 

DISPLAY WINDOW READS

 

  1) Display elapsed time   

 

 

 

 

 ELPSEd 

t

 

  2) Scan active channels   

 

 

 

 

 SCAn

 

  3) Display channel with highest reading 

   

      

  

 

HI  CHAN

 

  4) Display channel with lowest reading 

 

 

 

 

LO  CHAN

 

  5) Display deviation from SETPOINT 

 

 

 

 

dSP  dEN

 

  6) Display channel differential 

 

 

 

 

 

CH1 dIF

 

 

 

    

The channel numbers in Display Option #6 start with 

'CH1  dIF'

 and go up to 

'CH7  dIF'

 (

CH4  dIF

 for 4 channel units). 

Following this the display jumps back to Option #1  (elapsed time), and the cycle is repeated. 
 

Setup For Display Time 

 
The next parameter to be set is DISPLAY TIME.  This determines the number of 
seconds a channel's reading is displayed before moving to the next channel. The 
display will first show 

'dSPLy  t'

  (for Display Time), and then the current setting 

in seconds.  Use  

^v

 key (ref. Setup For High Scale) to set the desired DISPLAY 

TIME.  Once the desired DISPLAY TIME value is displayed, push 

SETUP

 key to 

enter that value and go to setup Relay as Latching or Non-Latching.
