• Insert the side of the temperature probe adapter marked with “+” in the
"V Ω °C/°F" jack [10] and the other side (“-”) in the "COM" jack [9].
• Hold the probe head to the device under test for ±30s and read the value
in the LCD display.
• Do not change the rotary function switch when the thermocouple is
connected to the meter.
7. Battery
• When the low battery indication appears, replace the internal battery.
• Always disconnect test leads when replacing the battery. Do not us the
device without batteries installed.
• The battery cover is located on the back of the device and is closed with
one screw. Remove the screw and open the battery compartment.
• Remove the battery and insert a new 9V battery following the polarity as
indicated in the battery holder. Only use a new battery of the same type
and specifications.
• Reinstall the cover and secure it with the screw.
•
Remove the battery when the device will not be used for a long time to avoid
leakage.
•
Do not recharge non-rechargeable batteries and do not throw in fire as they
may explode.
WARNING: handle batteries with care, observe warnings on
battery casing. Dispose of batteries in accordance with local
regulations.
Keep batteries away from children.
