Rixen TK-62 User manual

II. Care and Maintenance
1. This instrument functions with accurate Cold-junction
Temperature Compensation, but, if it is used in the place with
high temperature or high humidity, it will produce deference or
error message.
2. The temperature measurement of this instrument is based on
thermocouple. In order to avoid damage to the instrument and
electric shock, when the measured material has voltage or
static electricity, please clear the voltage or cut off the power
and then go to measure.
3. For getting the most accurate value, please keep it stable for a
while.
4. To avoid the incorrect reading, if the low symbol appears,
please replace the battery before using.
5. When not in use, please remove the battery from the
instrument, put the main instrument and all accessories into
the protection case and keep the kit in a dry, dust-free
environment out of direct sunlight.
6. Please contact the local agent or our customer service
department for any question or product repair.
TK-62 Digital Thermometer
Dual K/R Thermocouple Input
Instruction Manual
TK-62 Digital Thermometer has distinctively ergonomic
design for fast and easy operating. TK-62 is a gorgeous
temperaturemeasuring instrument which functions with dual
K/R thermocouples, and it can be used to monitor the whole
process of temperature changes from raw material to end
products; besides, it can be switched to general
K(CA)-TYPE or R(PR)-TYPE - for high temperature.
