IV. PRECAUTIONS AND PREPARATIONS FOR

MEASUREMENT

1. Before operating this instrument, please examine it to make
sure no shipping damage occurred.

2. Save all packing materials until you are sure that this unit can
normally operate.

3. Be sure the batteries are correctly placed in the case or the 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 there is a
good connection to the adaptor socket of the meter. Choose the K­type 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 be displayed in 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 continuous printing is required, 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 “

flickers.
