Omega DPS3200, DPS3100 System Configuration, Setup For Display Options, Setup For Display Time

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.
