4. MEASURING PROCEDURE
4-1 Type K measurement
1)Power on the meter by pressing the " Power button "
( 3-2, Fig. 1 ) once.
* After already power on the meter, pressing the
" Power button " > 2 sec continuously will turn off
the meter.
2)Meter default Temp. sensor type is Type K, the up Display
will show " K " indicator.
The default temperature unit is ( ), the method ℃℉
to change the Temp. unit from to or to ,℃℉ ℉ ℃
please refer to Chapter 7-6, page 20.
3)Insert the Type K probes into the " T1, to T12 input
socket " ( 3-9, Fig. 1 ).
The LCD will show the 8 channels ( CH1, CH2, CH3, CH4,
CH6, CH7, CH8 ) temperature value at the same time.
Page selection
If intend to show the other 4 channels ( CH9, CH10, CH11,
CH12 ) temperature value, just press the " Page
Button " ( 3-6, Fig. 1 ) once , the Display will show
those channels' Temp. value following, press the "
Page Button " ( 3-6, Fig. 1 ) once again, the Display
will revert to the 8 channels ( CH1, CH2, CH3, CH4,
CH6, CH7, CH8 ) screen.
* The CHx ( 1 to 12 ) value is the measurement Temp.
value sense from the Temp. probe that plug into the
input socket Tx ( 1 to 12 ) For example, the CH1
value is the measurement value sense from the Temp.
probe that plug into the input socket T1.
