Page 4 NOTE DPS3304 & DPS3314 are four channel units. Therefor e, any reference to channel numbers with respect to these models is for channels 1 through 4 only . DPS3307 and DPS3317 are seven ch annel units, and therefore, any reference to channel numbers for these models is for channels 1 through 7. DPS3304 & DPS3307 are base models that [...]

Page 5 DESCRIPTION DPS3300 Series instruments are multi-channel scanners that p ack a number of fun ctions into one un it. Tasks that require multiple monitors can now be accomplished by usi ng only a sing le unit. Si gnals from a num ber of different transducers can be brought into screw terminals that are convenien tly located on the back panel o[...]

Page 6 DISPLAYING PARAMETERS DPS3300 Seri es keeps track of various pa ramete rs and these m ay be displaye d by pushing ap propriate key s on the fro nt panel. The parameters that are tracked are: a) Channel' s high peak d) Channel wi th the lowe st reading b) Channel' s low peak e) Process devi ation of each c hannel from pre-program me[...]

Page 7 DISPLAY MODES DPS3300 Series has multiple display modes and can be programmed to either scan, display the chann el with the highest reading, displ ay the chan nel with the l owest readin g, deviat ion between channel's proc ess variable a nd a pre-pro grammed setpoint, di fference betwee n any two select ed channels or just run as a t i[...]

Page 8 Scan Mode When setup f or scan mode, i ndividual channels are displayed for a progra mmed period of time. At the end of that time period the, display automatically switches to the next chann el. For ease of reading, the display first shows th e channel number (Form at: 'CHANEL 1' ) and the n the process varia ble along with the pro[...]

Page 9 Deviation Mode In deviation display mode, DPS3300 Series will show the differential between a pre-programmed setpo int and process variable bei ng monit ored on each chan nel by the sca nner. Indi vidual setpo int for each ch annel is prog rammed du ring CH Setup and can be any value over the range of selected scale or the rmocouple being us[...]

Page 10 To get into S ETUP mode , push the SET UP key twice. The first push displays el apsed time and the second p ush brings the unit into the SETUP mode. SETUP mode is indicated by 'SETUP' in t he display window (t he SETUP LE D indicator will also be illuminated) followed by 'ENtR PC' (for ENt e R P ass C ode). The passcode [...]

Page 11 NOTE: To exit from any point dur ing SETUP procedure or to save the newly made changes, simply press and hold the RESET key until the display shows 'SAVING '. When the display shows 'SAVING', it is indicating that the unchanged and the newly m ade changes are being save d in the EEPR OM for pe rmanent st orage. It is imp[...]

Page 12 Setup For High Scale After setting a channel's decimal point position , the next parameter to be set is Hi Scale. This parameter determines what number will be displayed when the transducer puts out its maximum signal. For example, suppose a pressur e transducer pr oduces a 0 Vdc to 10Vdc si gnal which c orresponds t o 0psi to 150psi. [...]

Setup For Setpoint After setting a channel's TARE, the next parameter to be set is channel's SETPOINT. SETPOINT is used in Deviation Display mode. In this mode the display is[...]

Page 14 When this parameter is set for "Normally Open", the relay is open when it is deactiv ated (readings are below LIMIT), a nd closes when the cha nnel reading exceeds its LIMIT value. When this parameter is set for "Normally Closed", the relay is closed when it is deactivated (readi ngs are below LI MIT), and open when chan[...]

Page 16 The channel numbers in Display Option #6 start with 'CH1 dI F' and go up to 'CH7 dIF' ( CH4 dIF for 4 channel units). Following this the display jumps b ack to Option #1 (elapsed time), and the cycle is repeated. Setup For Display Time The next pa rameter t o be set is DI SPL AY TIME. This determ ines the number of secon[...]

Page 17 Setup For Channel Calibration After setting the Cold Junction Referen ce temp erature, the next step is a display of channels for calibration purposes. This allows easy calibration of each channel withou t the instrument scanning to the next channel. The display will show th e channel input reading in the form 'x-nnnnn' where x=ch[...]

The display will read '0002' --- or som e other value . 6. Adjust offset pot of instrument u ntil the display reads '0000 ' . 7. Push SETUP key -- the di[...]

Page 19 Once the desired channel has been selected, push 'HI/L O' key. Push ing it once will show the high peak attained by th e selected channel. Pushing it a second time will indicate the lo w process value (NOTE: The second push, to display valley, must be initiated before the display reverts to normal display mode). Before displaying [...]
