Introduction - Delta HD2114.0 Manual

This manual describes the characteristics and operating modes of the HD2114.0, HD2134.0,
HD2164.0 micromanometers, the HD2114B.0 barometer, and the corresponding HD2114.2,
HD2134.2, HD2164.2 and HD2114B.2 models with datalogger function. They are portable
instruments with a large LCD display. They perform measurements of absolute, relative and
differential pressure, and temperature.
Pressure is measured using an internal differential module that compares the atmosphere with
bottom of a fixed scale. With the PP471 module acting as an interface, the instrument can use all
the TP704 and TP705 series Delta Ohm probes to perform the measurements. The HD2114B.0 and
HD2114B.2 internal module measures the barometric pressure.
The temperature is detected using immersion, penetration, contact or air probes, with SICRAM
module or direct 4-wire probes. The sensor can be a Pt100, Pt1000 or Ni1000. The temperature
probes are fitted with a SICRAM module, with the factory calibration settings already being
memorized inside. On being turned on the instrument automatically detects these settings.
The HD2114.2, HD2134.2, HD2164.2 and HD2114B.2 instruments are dataloggers. They
memorize up to 36,000 samples, which can be transferred from the instrument connected to a PC
via the RS232C serial port or USB 2.0 port. The storing interval, printing, and baud rate can be
configured using the menu.
The HD2114.2, HD2134.2, HD2164.2 and HD2114B.2 instruments can transfer via the RS232C
serial port the acquired measurements to a PC or to a portable printer in real time.
The Max, Min and Avg function calculates the maximum, minimum or average values. The Peak
function can be activated with external probes connected to the module PP471 and detects the
presence of pressure peaks. Other functions include the relative measurement REL, the HOLD
function, and the automatic turning off which can also be disabled.
The instruments have IP66 protection degree.
If not otherwise specified, this manual's descriptions are intended to be applicable to all
models.
