• Insert the side of the temperature probe adapter marked with “+” in the

"V  °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.
