WARNING – The Thermocouples of the Stem Psychrometer Chamber are
made from very fine wire only 25 µm in diameter. NOTE: Human hair is on
average 100 µm thick. You will require a dissection microscope with a 20X
magnification objective setting to view the thermocouples. You cannot see
them or manipulate their position with the naked eye. Thermocouples are
easily broken if handled incorrectly by unprepared operators. Please WATCH
the video Adjusting the Thermocouples : https://www.youtube.com/watch?

before removing the chamber’s calibration lid.

System Requirements

Hardware:

The ICT Instrument software does not require a powerful computer.
Minimum Recommended System Specifications:
Intel Atom 1.66 GHz and 1GB RAM or higher.

Software:

Screen Resolution:

The ICT Instrument software is written to a fixed screen resolution of 857 x 660
(it does not Auto Resize) and works best on current model laptops that have a
screen size of 11.6” or larger and a default screen resolution of 1366 x 768 (the
vertical height of 768 being most important otherwise you can't see the bottom of
the software window).

The ICT Instrument software is compatible with the following
Windows Operating Systems:
a.
b.
c.
d. Windows Virtual OS run from a Mac computer

Windows Vista
Windows 7
Windows 8 and 8.1

Power Requirements and Charging the PSY1 Internal Battery

The PSY1 is a self contained instrument that incorporates a lithium polymer
battery. Before using the instrument, this battery MUST be charged.
To choose from a range of charging options see :
Connecting a Power Supply to the Instrument (pages 7 to 11).

The unique power-bus plug design was developed by ICT International to
simplify the electrical wiring process. It minimises the need for custom tools in
thefield, requiringonlythattheoutercablesheathbestrippedbacktoexpose
thecopper wire. See section: Connecting a Power Supply to the Instrument
(page7)Noothertoolsarerequiredwithallnecessarycomponentsfully
incorporated into the instrument design. Retaining straps ensure that the
power-bus plugs do not separate from the instrument when removed from the
power-bus during wiring preparation and connection of external power.

The PSY1 can be charged from a range of external voltages via the Bus Plugs,
however there are limits. For the PSY1 to correctly charge, the external power
supply must be within a voltage range of 8Volts DC to 30Volts DC at all
times. If the voltage falls below 8Volts DC the logger will automatically stop
using the supply to charge the internal battery. 30Volts DC is a predetermined
maximum voltage that the PSY1 can handle. Supply voltages that exceed this
level are not recommended and may cause accidental triggering of the
protection circuitry. Triggering this circuit may result in semi-permanent
disabling of the external power which will require the PSY1 to be sent back to
ICT for repair.
