Page 5 - NOTE
Page 4 DESCRIPTION DPS3000 Series instruments are multi-channel scanners that pack a number of functions into one unit. Tasks that require multiple monitors can now be accomplished by using only a single unit. Signals from a number of different transducers can be brought into screw terminals that ar...
Page 6 - DISPLAYING PARAMETERS; Table 1. How to Display Parameters
Page 5 DISPLAYING PARAMETERS DPS3000 Series keeps track of various parameters and these may be displayed by pushing appropriate keys on the front panel. The parameters that are tracked are: a) Channel's high peak d) Channel with the lowest reading b) Channel's low peak e) Process deviation of each c...

Elapsed Time display format is 'HH.MM.SS' for hours, minutes, and seconds. The desired display mode is selected during SY...
Page 8 - Types of Deviation Displays
Page 7 Display time for each channel is programmable from 1-999 seconds (16.65 min.). This is useful for adjusting display time to a rate which is consistent with the type of process being monitored. Scan time for each channel is independent of display time. This permits programming long display tim...
Page 9 - Difference Mode; SETUP
Page 8 a) The first one is a momentary display in which the deviation is indicated for a short time. Following this brief display time, the unit reverts to its normal mode of operation (scanning, differential, timer etc.). To achieve this, first select the channel whose setpoint deviation is desired...
Page 10 - CH Parameter List
Page 9 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 SETUP key...

Page 18 - PEAKS; PROGRAMMING FLOW CHARTS:
Page 17 PEAKS A very useful function of DPS3000 is tracking the highest (peak) and the lowest (valley ) point attained by each channel. This is particularly helpful if an operation is not being constantly watched or is left unattended (e.g. overnight). Since high and low points for each channel are ...
