until the power is switched off. The probe switches to the energy-saving mode (>1mA) and
takes no more measurements until the power has been switched off.
For use with:
TRIME-HD analog display module
Analogue data loggers with relay (Special application)
PC A/D converter boards with relay (Special application)
1.1.3
Operation mode C (Cyclic measurement)
TRIME-PICO IPH takes measurements at a freely configurable measurement rate (from 8s..24h).
Once the measurements have been taken (2..3s) the measured values are supplied as analogue
output signals. Until the next measurement is finished, the values of the previous measurement
are available as analogue signal. In standby until the next measurement is executed the probe
consumes 8..10mA @ 12V/DC.
For use with:
Mains power (Special application)
Analogue data loggers with mains power (Special application)
PC A/D converter boards (Special application)

External power supply
The TRIME-PICO IPH does not contain any kind of power supply, so that it has to be supplied
externally. At the portable systems PICO-BT and TRIME-HD this power will be provided by an
internally rechargeable battery.
If the TRIME-PICO IPH is used with the GlobeLogger it will be supplied by the IMP-Bus.
For the use with other stationary systems it has to be ensured, that the TRIME-PICO IPH will be
supplied by an external source with 7..24V/DC.

Installation hints
Please assure careful installation of the probes with close contact between tube and soil. It is
important to avoid air pockets around the tubes as the highest measuring sensitivity is directly
around them.
Air pockets around the tube wall can reduce the measured moisture reading. Where saturated
soils are involved, water-filled air pockets will result in an exaggerated reading.
IMKO supplies drilling equipment for an optimal preparation of the installation point, avoiding
air gaps around the tube and compaction of soil.
