IV. PRECAUTIONS AND PREPARATIONS FOR
MEASUREMENT
1. Before operating this instrument, please examine it to make
sure no shipping damage occurs. Otherwise notify your dealer.
2. Save all packing materials until you are sure that this unit can
normally operate.
3. Be sure that batteries are correctly placed in the case or
adaptive 9V Adaptor is in correct connection.
4. An unsecured battery cover will cause error measuring.
5. To avoid battery leakage problem, remove batteries if this meter
will not be used for a long time.
6. Do not use or store this meter outside the operating / storage
environment.

V. OPERATING PROCEDURE
1. This meter can be supplied with batteries or DC 9V AC Adaptor.
If using batteries :
Remove the rear cover, and install batteries, pay attention to the
polarity of battery socket. If using 9V Adaptor, make sure that it is
in good connection to the Adaptor socket of the meter. Choose the
K-type temperature probe for your application and insert it into T2
the temperature probe socket. Insert Humidity/Temperature (T1)
probe into T1 the meter socket.
2. Press the button to power on the meter, the current date and
time will displayed about 3 seconds. If “- - -” appears, it indicates
no probe or the probe is broken.
3. T1 indicates room temperature, T2 indicates K-type thermocouple test
value.
4. Printing data :
 Press PRINT one time to print one set data.
 If need continuous printing, press and hold down PRINT button,
until LCD display “INTV” mark and enter continuous interval printing
mode, the printer will print data, as follows :

Press PRINT or FEED key to exit printing mode.
 When the meter is powered on, if the printing function setting is
“ON”, and now time is interval printing start time, the meter will
enter to continuous interval printing mode and start printing.
※
Press PRINT or FEED key to exit printing mode.
※
The interval printing function works only when the start
printing time is earlier than the stop printing time, and interval
print time can not be longer than 24 hours.
Caution : Before printing, please check thermo-paper is not clipped by
thermo-paper cover, if anything interrupts the printer, the
meter will shut off the printer power, and “ ” symbol
flickers.
