the indication of the elapsed time. Maximum time indicated is 999.59.59 hours. 
 
To reset the timing and start it all over again, first push the TIME key and while keeping it pushed, press the RESET key. The 
time will reset and start over from 000.00.00 hours.  
 

SETUP: 

 
Setup mode provides a means to customize the monitor to suit a particular application. It allows programming such parameters as 
temperature units, limits, display mode, relay deadband, etc. 
 
SETUP mode has 2 sections: 
  a) 

the 

SYS setup section to set system parameters 

 

 

b) the CH setup section to set channel parameters for each channel. 

 
To get into SETUP mode, push the SETUP  key twice.  The first push displays elapsed time and the second push  brings the unit 
into the SETUP mode.  SETUP mode is indicated by  'SETUP' in the display window  (the SETUP LED indicator will also be 
illuminated) followed by    'ENtR  PC' (for ENteR Pass-Code).  The pass-code feature has been provided to keep unauthorized 
personnel from changing any parameters. Each of the five keys on the front panel are labeled with a number in the lower right 
corner.  The pass-code is a four digit combination of these numbers. Enter the pass-code when the displays reads 'ENTR PC' . 
For DP3300 units, the PASS-CODE # is 3254. 
 
Three attempts at entering the correct pass-code are allowed. 'HELP' shows up in the display window if the attempted pass-code 
is wrong.  If a person fails in three attempts the system will go back to normal display mode. To make another attempt at this 
point one has to get into SETUP mode again. 
 
Three keys are used during setup --- SETUP, < NEXT >, and ^v. If, at any point during SETUP, it is desired to get out of 
SETUP, push and hold the RESET key until the display reads 'SAVING'. The SETUP key takes you from one parameter to the 
next. For Example,  if you are setting up Channel ON/OFF,  then after getting the desired value push SETUP key to setup for 
Degrees C/F.  The  <NEXT> and ^v keys are used for programming the values of parameters such as limits, setpoints, etc. 

 
EXITING SETUP: 

 
 To exit from any point during SETUP procedure or to save the newly made changes, simply press and hold the RESET key until 
the display shows 'SAVING'. This indicates that the unchanged and the newly made changes are being saved in the EEPROM for 
permanent storage. 
 
Once the correct pass-code has been entered, the display shows 'SYS   CH',  with CH blinking.  At this point the operator may 
choose between making channel settings (CH), or system settings (SYS).  Use ^v key to toggle between CH and SYS modes.  
When the desired mode is blinking, press the SETUP key to begin setup of the parameters for that mode. 
 
 

CHANNEL CONFIGURATION 

 
After entering the correct pass-code and selecting the blinking 'CH' (ref. SETUP section), the display shows 'SLCt  CH' (for 
"Select Channel"). Use ^v key to display the desired channel. The selected channel will be displayed in the format 'CHANEL x' 
(where x=channel#). Once the desired channel # is displayed, push SETUP key to go on to setup parameters for the displayed 
channel #. 
 

 
The display will briefly show  'IP  TYPE' (for "Input type") after which current input type for the channel will be displayed.  
Various inputs are: J  T/C, CR.AL  T/C (Chromel Alumel, type K  T/C), T  T/C,  E  T/C, CURRENT, VOLTAGE or PULSE 
(Refer to model number on the unit to find input type).  To change the displyed input, push ^v key till appropriate type is 
displayed. Push SETUP key to move to the next step. 
 
NOTE 1: Whenever input type is changed, the unit automatically clears the previously entered engineering display units. 
Therefore, do not forget to enter new engineering units (ref. Display Units section) or the respective  channel will display '. . .' 
(three dots) when displaying a process value.
