Cautions
To avoid possible damage to the instrument, follow these guidelines.
DO NOT change the values of the calibration constants from the factory set
values unless you are recalibrating the instrument. The correct setting of these
parameters is important to the safety and proper operation of the instrument.
Allow sufficient air circulation by leaving at least 3 inches of space between the
thermometer and nearby objects.
For CE compliance and for performance, use only the AC adapter shipped with
the instrument by Hart Scientific. If the AC adapter needs to be replaced, con
-
tact your an Authorized Service Center.
This instrument and thermometer probes are sensitive and can be easily dam
-
aged. Always handle these devices with care. DO NOT allow them to be
dropped, struck, stressed, or overheated.
Probes are fragile instruments which can be damaged by mechanical shock,
over-heating, and absorption of moisture or fluids in the wires or hub. Damage
may not be visibly apparent but nevertheless can cause drift, instability, and
loss of accuracy. Observe the following precautions:
DO NOT allow probes to be dropped, struck, bent, or stressed.
DO NOT overheat probes beyond their recommended temperature range.
DO NOT allow any part of the probe other than the sheath to be immersed in
fluid.
DO NOT allow the probe hub or wires to be exposed to excessive
temperatures.
Keep the probe wires clean and away from fluids.
DC Battery Pack Option:
If the battery charge is not sufficient (less 10.25V), the instrument will continue
to function while taking incorrect measurements. DO NOT utilize the instru
-
ment for measuring when the Low Voltage Indicator is lit.
