IV. GENERAL PRECAUTIONS AND
PREPARATIONS FOR MEASUREMENT
1. Before operating the instrument, examine it to make sure it
is not damaged.
2. Retain all packing materials in case the unit has to be
returned for repair or calibration.
3. Ensure the batteries are correctly installed before turning
the instrument on. If using an external power adapter,
ensure it is suitable, has the correct polarity and is
undamaged.
4. Ensure the battery cover is correctly fitted, otherwise
measurement errors may occur.
5. If the instrument is to be stored for a long time, remove the
batteries to prevent leakage and corrosion.
6. Do not use or store this meter outside the operating or
storage environmental conditions qouted in the
specifications.
V. OPERATING PROCEDURE
1. Before using the instrument, install the batteries as follows:
Remove the rear cover, and carefully install Qty 6 AAA
batteries, observing correct polarity.
Insert the supplied temperature and humidity probe plug into
the corresponding meter socket. If required, select a suitable

9
K-type thermocouple probe and insert the plug into the
miniature thermocouple socket.
2. Press the button to turn the meter on. The current date
and time will appear on the display for approximately 3
seconds. If “- - -” appears on the display, it indicates no
probe is connected, or the connected probe is open circuit.
3. T1 indicates temperature sensed by the combined
temperature/humidity probe, whilst T2 indicates the temperature
sensed by the K-type thermocouple (if connected).
4. Printing data:
cPress the PRINT button once to print one set of data as
shown on the LCD.
dIf continuous printing is required, press and hold down the
PRINT button, until the LCD display shows the “INTV” mark
and enter continuous interval printing mode. The printer will
print data as follows:
INTV 00 : 06

Press the PRINT or FEED button to exit continuous printing
mode.
eWhen the meter is on, if the continuous printing function
setting is “ON”, and the current time is the interval printing
start time, the instrument will start continuous interval
printing mode and begin printing.
※Press the PRINT or FEED button to exit printing
mode.
※The interval printing function works only when the start
printing time is earlier than the stop printing time. The
interval printing duration cannot be set to greater than
24 hours.
Caution: Before printing, ensure the printer paper is not trapped
by the printer cover, if the printing process is interrupted
by a mechanical fault, the printer, will stop printing and
the “ ” symbol on the LCD will flicker.
VI. SETTING MODE

11
Press the “ MENU ” button to enter function setting mode. Each
subsequent press of this button selects setting parameters in
sequence (printer on or off, interval printing time, start printing
time, stop printing time and calendar setting). When in setting
mode, the adjustable parameter will flicker until setting is finished.
Press the or button to select the required parameter to
set, then press the or button to increase or decrease
the parameter value.
The parameter setting sequence and LCD display appears as

VII. INTERVAL PRINTING SET-UP
To setup interval printing with a 24 hours limitation.
1. Press the MENU button to enter setting mode; setting
print operation is turned ON.
2. Select the printing interval time setting mode. Set the
required “seconds” and “minutes” (from 00:06 to 59:59).
3. Select the required time to start printing. Set the
“minutes” and “hours” (from 00:00 to 23:59).
4. Select the required time to stop printing. Set the
“minutes” and “hours” (from 00:00 to 23:59).
5. Press the MENU button to exit setting mode. The LCD will
display a “ ” mark at the left upper corner.
Note: The start time must be earlier than the stop time,
otherwise the buzzer will sound to warn the settings
are incorrect. The instrument will not accept the
settings when the MENU button is pressed.

VIII. BATTERY REPLACEMENT
When the battery power is not sufficient to provide accurate
measurements, the symbol will appear on the LCD.
Replace the exhausted batteries with qty. 6 x 1.5V AAA size cells.
1. Turn the instrument off and then disconnect the
temperature/humidity probe and any K-type thermocouple.
Remove the battery cover.
2. Remove batteries from the holder and replace with qty. 6
new 1.5V size AAA alkaline batteries.
3. Refit the battery cover and check the instrument operates
corrrectly.
IX. RECALIBRATION PROCEDURE
The thermometer should be calibrated once a year to ensure
its continued accuracy. Contact RS Components for further
details of calibration service. The address is given at the end
of these instructions.
