Error No. Error Text
Possible Cause of Error
30
TDR may be defective TDR electronic or probe cable defective
31
TDR level not found
TDR level searching lasted too long, may occur with bad signal quality
due to conductive soil or material
32
Probe not connected
No probe connected or probe connector defective
33
Salinity too high
Electrical conductivity of soil/material too high
34
Invalid probe data
Data in probe connector not plausible or probe connector defective
35
Battery is empty
Supply voltage too low or battery empty
1.1.5 Battery
Operation
The internal chargeable battery has a capacity of 600 mAh, which allows about 300 measurements.
This is only an approximate value and dependent on a lot of influences, like ambient temperature,
pauses between the measurements, measured material and age of the battery. The measuring
operation should be terminated, as soon as the error message “Battery is empty“ appears.
If the battery capacity is not sufficient or battery operation is not desired, at all, an external battery or
power supply may be connected via the RS232 connector.
Attention: Charging is only allowed with the supplied ACS charger!
1.1.6 Battery
Charger
The micro controlled charging method of the ACS charger guarantees an optimised battery lifetime.
1. Regarding the battery lifetime the “discharging“ mode is most favourable. It is started by pressing
the yellow button. However, it is not harmful for the battery to use the “charging“ mode if the
charging shall be carried out fast, i. e. in up to 4 hours. The “discharging“ mode lasts between 6
and 7 hours.
The charger can remain connected as long as one likes. The battery can not be damaged by it.
Please refer to the charger operating instructions on page 21.
1.1.7
External Power Supply
An external power supply (9..15V/300mA) can be connected via the RS232-cable. In this case the
internal battery is disconnected and the instrument is supplied by the external power only. It doesn’t
switch off then, but remains on as along as the external voltage is connected. Therefore the data
logger operation requires an external power supply.
It is even possible to connect an external battery if the capacity of the internal battery is not sufficient.
1.1.8
Data Logger Operation
The TRIME-FM comes with an analogue output of 0..1V in order to make data logging with external
devices possible. For this data logger operation the TRIME-FM should measure automatically. The
cyclic measuring mode (mode C) can be set by the program TRIMESET, whereas the cycle time can
be chosen.
1.1.9
PC-Connection via RS232
The TRIME-FM can be connected to a PC via the RS232 connector and the appropriate cable, in order
to carry out data logging, changing the operating mode, or calibration. As long as the PC is connected
the power-off automatic is disabled to prevent switching off. It is to be considered that the internal
battery is discharged as long as the PC is connected.
