DPG 2400 Series
3. Product Description
3.1 General Description
The DPG 2400 is the lowest accuracy single-range pressure measuring instrument
available in the Mensor DPG family. With an uncertainty of 0.03% FS, and a small
package design, this unit is perfect for desk top monitoring of pressure changes and
for use in Production and Test environments. Temperature compensation from 15 to 45
degree C permits use in this temperature range without degradation of accuracy.
The unique design of the DPG 2400 has modest features and simple menu options. It
has a standard RS-232 serial output port that can be used for remote communications.
It can display measured pressure along with peaks or null. Other features are a mono-
chrome LCD display, null capability, a single silicon sensor and it is powered by a wall
transformer.
Optional features include external dual differential relief valves, externally mounted relief
valves, RS-485 communications (100 ft cable length recommended), and a rack mount
kit.
3.2 Display
Several different display screens are presented while operating the DPG 2400. Each
screen is arranged into blocks of information, generally organized into columns and
rows. These screens are each described in further detail in Section 6, “Local Opera-
tion”, and in Section 7, “Remote Operation”.
3.3 Power Supply
The power adapter is utilized to provide power to operate the DPG 2400. It produces 12
VDC @ 830 mA max.
3.4 Serial In/Out Communications
The serial port can be used to configure and calibrate the DPG 2400, or to read the out-
put of its sensor. Depending on how your DPG 2400 was ordered, the instrument came
with either RS-232 or RS-485 serial port communications. Both are explained below.
The RS-232 serial port is configured as 9600 baud, 8 data bits, 1 stop bit and no parity.
It is designed as a 9-pin DCE device so that a straight pin to pin cable can be used to
connect it to a standard PC serial port.
