Clearing faults, service and calibration
Service
If you have tried to clear a fault according to above but the fault remains, contact your nearest
Tour & Andersson office. If the unit has to be sent in for repair,
please enclose a description
of the fault .
Calibration
A calibration certificate for TA-CMI is issued after the delivery control. The equipment used is
traceable to national standards according to ISO 9001 or equivalent. Customers, who want a
regular calibration of the TA-CMI can order that from Tour&Andersson AB. Please mark
“Calibration” when you order. How frequent calibration of the instrument is necessary are
dependent upon usage and if it is required according to standards. As a general rule a calibra-
tion interval of 1 year is recommended.
Clearing faults
Automatic restart
If the instrument detects a lockup condition (the keyboard is not working), the instrument
restarts itself within 5 seconds. All saved data in the instrument will be unchanged.
No radio communication between instrument and sensor units
If the “radio off” symbol is displayed at top of the LCD, start radio
communication by connecting the cable between the instrument and sensor
units (see page 8).
Note! When you connect the instrument unit via the cable to a sensor unit,
you synchronise that particular sensor unit to communicate with your
instrument unit.
Incorrect function
If the instrument works incorrectly, i.e. due to
static electricity discharge, keep the start key
depressed and within one second also press the
first function key and the left key. This makes the
instrument restart but all saved data in the instru-
ment will be unchanged.
Blank LCD
If it is not possible to see the menus in the LCD,
press the Escape key for more than 2 seconds. The
LCD contrast will increase as long as the Escape
key is depressed.

During storage
*)
.......................................................................................................... -20 – 60°C
*) Do not leave water in the sensor when there is a risk of freezing.
Storage above 40°C reduces battery life.
