MEASURING PROCEDURE
1.
Push the “power off button” (3-2, Fig. 1) to let the instrument power “ON”.
2. Determine temperature unit to °C or °F by pushing the “ °C/°F Button “ (3-4, Fig.
1) Then the display will show the temperature unit of °C or °F.
3. Determine the display resolution to 0.1° or 1° by pushing the “1°/0.1° Button”.
4. One probe measurement:
Insert one temperature probe plug into the socket T1 (3-11), then push the
“Function Button” (3-8, Fig. 1) until the display show the marker “T1” display will
show the temperature reading that measured from the probe.
5. Two probe (dual channel) & differential measurement:
a. Insert second temperature probe plug into the “T1 Socket” (3-11, Fig. 1).
b. Insert second temperature probe plug into the “T2 Socket” (3-12, Fig. 1).
c. The main display (upper display) will show the temperature reading of the
first probe (T1) & the lower display will show the temperature reading of
second probe (T2), push the “Function Button” (3-8, Fig. 1) until “T1” appears
on the display.
d. The main display (upper display) will show the temperature reading of second
probe (T2) & the lower display will show the temperature reading of the first
probe (T1), push the “Function Button” (3-8, Fig. 1) until “T2” appears on the
display.
e. The main display (upper display) will show the differential temperature
reading of the first and second probe (T1-T2) and the lower display will show
the temperature reading of the first probe (T1), push the “Function Button” (3-
8, Fig. 1) until “T1-T2” appears on the display.
DATA HOLD
1.
During the measurement. Push the “Data Hold Button” (3-3, Fig. 1) will hold the
display values & LCD will show the “D.H” marker.
2. Push the “Data Hold Button” again will release the data hold function.
DATA RECORD
1.
The DATA RECORD function displays the maximum, and minimum readings. To
start the DATA RECORD function, press the “Record Button” (3-6, Fig. 1) once.
“REC” will appear on the LCD display.
2. With the “REC” appearing on the display.
3. Push the “CALL Button” (3-7, Fig. 1) once, then the “Max” marker along with the
maximum values will appear on the LCD display.
4. Push the “CALL Button” once, then the “Min” marker along with the minimum
values will appear on the LCD display.
5. When running the “Record” function, pushing the “Record Button” once again
will stop the “Record” function.
6. After stopping the “Record” function, the marker of “REC”, “Max”, “Min” will
disappear.
MAIN PROCEDURES
OPTIONAL MEASURING PROCEDURES
MEASURING CONSIDERATION
Insert the probe plug into the temperature input socket T1 (3-11) of T2 (3-12), taking
care to observe the correct polarity. Greatest accuracy is achieved when the probe
plug is first inserted into the thermometer socket (T1,T2), or if the probe is changed,
the plug must be allowed to stabilize at temperature of the socket, which is in thermal
contact with cold junction compensation device. This will take a couple of minutes and
only applies if the probe plug has previously been exposed to an ambient temperature
different to that thermometer.
BATTERY REPLACEMENT
When the left corner of LCD display show “LBT”, it indicates a normal battery output of
less than 6.5V – 7.5V. It is necessary to replace the battery. However, in—spec
measurement may still be made for several hours after low battery indicator appears
before the instrument becomes inaccurate. Slide the Battery Cover (3-10, Fig. 1) away
from the instrument and remove the battery. Replace with 9V battery (heavy duty type)
and replace the cover. Make sure the battery cover is secured after changing the
battery.
