4. MEASURING PROCEDURE
1)Connect the " Probe Plug " into the " Input Socket ".
* The input socket of PT-100 ohm is the " 3-12, Fig. 1 ".
* The input socket of Thermocouple type K/J/T/E/R is the
" 3-11, Fig. 1 "
2)Select the " Power Off/On Button " ( 3-7, Fig. 1 ) to " On "
position.
3)Select the sensor type ( PT-100 ohm, type K, type J, type
T, type E, type R ) by push the " Sensor Select Switch "
(3-5, Fig. 1).
4)Determine the display resolution to 0.1or 0.01by pushing
" 0.10.01Button " ( 3-8, Fig. 1 ).
* The meter can be selected the different
resolution 0.01 蚓, 0.1 蚓, 0.01 蚌, 0.1 蚌, 1 蚓,
1 蚌.
The relation of resolution/range/different sensor
type, please refer the " 2-2 Electrical
Specifications ", page 2.
* Push the " 0.10.01Button " once again, the
display will get the alternation of high resolution
and the low resolution.

5)
Data Hold :
During the measurement, push the " Hold Button " ( 3-2,
Fig. 1 ) will freeze the display value & LCD will show the
" HOLD " marker. Push the " Hold Button " once again
will release the data hold function.
6)
Relative Measurement
@During the measurement, the circuit will memorize the
last measured values if push the "REL. Button " ( 3-9,
Fig. 1 ) at once, then LCD will show "0" & a " REL "
marker appear on the LCD display.
@The new measured temperature values will deduct
above memorized " last measured value "
automatically.
@It will release the Relative Measurement function if
push the REL. button at once again, at same time the
"REL" marker will disappear.
Considering:
When marking the " Data Hold " & " Data Record "
measurement, the Relative function is prohibited.

6)
Data Record ( Max. and Min. reading )
The Data Record function displays the maximum and
minimum readings. To start the Data Record function,
press the " Record Button " ( 3-3, Fig. 1 ) once.
" REC " symbol will appear on the LCD display.
With the " REC " symbol on the display :
a)Push the " Recall Button " ( 3-4, Fig. 1 ) once, the
" Max " symbol along with the maximum value will
appear on the display.
b)Push the " Recall Button " again, the " Min " symbol along
with the minimum value will appear on the display.
c) To exit the memory record function, push the " Record
Button " once again. The display will revert back to the
current reading.
7)
Offset Value adjustment
@Caused by the environment temperature change or other
reasons.... The measuring value of the thermocouple
sensor input (type K/J/T/E/R) may exist the drift of small
digits.
@If find that the measuring values exist deviation of small
digits especially when measure the low temperature, then
can adjust the " Offset Adjust VR " to make the
compensation until get the correct reading exactly.
The offset adjustment procedures are following:
a)Plug in a type k thermocouple probe to the input
socket & Set the " Sensor Select Button " ( 3-5, Fig. 1 )
to the " Type K". Now the meter is measured the
environment Temperature value.
