DP3300 Series User’s Manual DESCRIPTION: A highly versatile series, DP3300 offers a unique combination of two analog channels or two pulse input channels or a combination of pulse (square wave) on one channel and an analog signal on the other. This feature allows it to be used as counter, rate, RPM or a frequency monitor along with displaying an analog signal such as 4-20ma loop current, voltage or millivolts or a temperature signal from thermocouples, RTDS etc. For example, flow an

DP3300 Series User’s Manual RESETTING PEAKS Peaks can be reset to current process value e.g. if channel 1 is reading 200 C, its peaks can be reset to 200. This will allow tracking from the current process reading. To reset high peak, first select the channel whose peak is desired to be reset (by pushing the ‘CH. SEL’ key). Once the channel has been selected, push the ‘HI/LO’ key and keep it pushed. The display will read 'CHx HI' (x=channel #) following which the value of high peak w

(NOTE: In the RPM mode, the rate time base must be smaller than the selected filter value. If not, the system will automatically consider the filter value as the time base for rate calculation. Also, a difference of 0.500 is recommended between the filter and time base). FREQUENCY MONITOR: DP3300 moni

DP3300 Series User’s Manual RESETTING COUNT: The COUNT shown for each channel can be reset to zero or preset for a count down (depending on counter mode) at any time. To reset the count manually, first select a channel by pushing CH SEL key and ,while keeping the CH SEL key pushed, push the RESET key simultaneously. The display will read 'RESET' and then the reset value of zero will be displayed. If the counter is set for count down mode, then the display will preset to the value that w

DP3300 Series User’s Manual ‘Channel ON/OFF’ Setup After displaying input type, the next step turns a channel ON or OFF. This determines whether a channel is scanned and displayed or not. If for any reason a channel is not being used, it should be turned OFF. This will prevent the unit from spending any time scanning it and also from displaying a 'HELP' message if there is no signal connected to its input. If a channel is OFF, the display will show 'CHx OFF' , and if it is ON the dis

DP3300 Series User’s Manual suppose a flow transducer outputs a 0.130Vdc to 5.000Vdc signal which corresponds to a flow rate of 0 to 40 gal./min. Then to make the 0.130Vdc correspond to a display of 0, set OFFSET =0.130. NOTE: If the input type is CURRENT, the Offset value is entered in milliamps. If the input type is VOLTAGE, the Offset value is entered in millivolts. After pushing SETUP key at the completion of Setup For Low Scale, the display will briefly read 'OFFSEt', and th
