DP3300 Series User’s Manual
Page4
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 and temperature or flow and pressure can
easily be monitored in a single unit.
On the analog channel, signals from thermocouples, RTDS or thermistors are linearized and displayed in degrees Centigrade or
Fahrenheit. Voltage and milliamp signals (4-20ma etc.) are displayed in engineering units that correspond to the process being
monitored. Scaling is accomplished through front keys and does not require any tedious formulas.
The Pulse (or square wave input) channel funct i ons like four monitors in one. It can be progr ammed as an up/down counter, rate,
rpm or frequency monitor. In counter mode, the channel can count up or down to a maximum count of 9,999,999 and also offers
three presets along with built in delay timers. As a rate indicator, it offers a programmable time base from 1.000 to 9999.999
seconds.
In RPM mode, the channel counts incoming pulses and displays the data as revolutions per minute. In frequency mode, an internal
crystal reference is used to indicate the frequency of incoming pulses (low frequency mode only). Measured frequency range is
from 1Hz to 1 megahertz. Two modes of operation are supported:
1. High frequency mode (resolution = 1Hz)
2. Low frequency mode ( resolution = 0.01 Hz)
NOTE: Check model number for the type of input and display units ---- thermocouples, 4-20ma, 0-5Vdc , or 0-10Vdc
etc...
DP3300 saves all the programmed parameters in an EEPROM (electrically erasable programmable read only memory).
An EEPROM stores the programmed parameters even when the power is removed from the unit. However, it is important to note
that if the parameters are being changed during setup, they must be saved in the EEPROM by pressing and holding the RESET
key till the display reads 'SAVING' (also described under SETUP). If the parameters are NOT saved and the power is removed
from the unit, any newly changed values will be lost (the unit will, however, maintain the old values).
