LOW BATTERY WARNING AND BATTERY REPLACEMENT
If the battery voltage falls below acceptable levels, a beep sounds every 30
seconds. From that moment there remains about 1 hour autonomous oper-
ation, however the battery should be replaced as soon as possible.
To change the battery turn the battery retaining screw in an anti-clockwise
direction. After replacing it (with an ordinary 9V/006P battery), close the
door, inserting the tag on the door into the slot provided, and turn the
screw in a clockwise direction.
Ensure that the instrument is switched off before changing the bat-
tery.
FAULTY OPERATION WHEN SWITCHING ON AFTER
CHANGING THE BATTERY
Repeat the battery changing procedure, waiting for a few minutes to allow
the circuit condeser capacities to be completely discharged, then insert the
battery.
WARNING
*
If the instrument is not be used for a long time the battery must be
removed.
*
If the battery is flat it must be replaced immediately.
*
Take steps to avoid leakage of liquid from the battery.
*
Use good quality leakproof batteries.
Warning for sensors and probes
The TP 870 series of Pt100 temperature probes are sturdy, the element on
which the platinum wire is wound is alumina. For long life avoid hard
knocks, especially at temperatures above 400°C, or thermal shocks.
The shell is made in AISI 316 stainless steel.
In the combined conductivity and temperature probe the outer tube is
made of Pocan and the temperature sensor of Platinum.
When using, check that these materials are compatible with the liquid in
which the measurement is to be taken.
The sensor must be kept in a dry place. Check regularly that there are no
encrustations on the sensible part of the probe. Any encrustations may be
removed with a damp rag and detergent.
Particularly stubborn encrustations may be removed with kitchen type soap
pads. After you have cleaned the rings, do not touch them with your hands.
