INTRODUCTION
The HD2178.1 and HD2178.2 are portable instruments with a large LCD display. They measure the
temperature using immersion, penetration or air contact probes. Input A accepts K, J, T, N or E
thermocouple type probes. Input B accepts probes with SICRAM module and Pt100 sensor probes
or probes which sensor can be a Pt100 4 wires, Pt1000 or Ni1000 2 wires.
The probes are fitted with automatic detection module, with the factory calibration settings already
being memorized inside.
The HD2178.2 instrument is a datalogger. It memorizes up to 80,000 samples which can be trans-
ferred from the instrument connected to a PC via the RS232C serial port or USB 2.0 port. The log-
ging interval, printing, and baud rate can be configured using the menu.
The HD2178.1 and HD2178.2 models are fitted with an RS232C serial port and can transfer the ac-
quired measurements in real time to a PC or to a portable printer.
The Max, Min and Avg function calculate the maximum, minimum or average values.
Other functions include: the relative measurement REL, the HOLD function, and the automatic
turning off that can also be disabled.
The instruments have IP66 protection degree.
This manual describes the HD2178.1 and HD2178.2 models: if not otherwise specified, the de-
scription is intended to be applicable to both models.
