Introduction
The Druck DPI 150 high accuracy, single-range pressure indicator uses the
Druck IDOS sensor to produce pressure readings in units of pressure
measurement and aeronautical units.
The instrument is contained in a moulded plastic case with integral rubber
feet for workbench surface use. Function keys, on the front panel, allow the
user to access an operating menu and set-up menu. Two more menus,
supervisor and calibration, allow the user to change the PIN codes,
communications settings and display language and for calibration of the
pressure sensor. A four digit PIN code protects both these facilities. The
electrical and pressure connections are located on the rear panel.
The instrument is supplied, as standard, with a RS232 data interface. Options
available include an IEEE 488 interface, an analogue output, a barometric
reference, negative calibration, external sensor and panel mount kit.
