Lead resistence of sensors can be considered up to a value of 50
Ω as follows:
The temperature measurement range is now selected.
Ø
The LCD now displays. the zero resistance value. So that you can recognize that
this is the resistance correction value on the temperature measuring range, the “
0
C” character is simultaneously shown.
Ø
You can set the line resistance correction value as follows:
Press the DATA-MIN/MAX pushbutton (3) to increment the value, or the
AUTO/MAN pushbutton (4) to decrement the value. Each time the
pushbutton is briefly pressed, the value changes by one digit. you pass
through fast, when you press the pushbutton longer.
Ø
Briefly press the yellow multi-function pushbutton (5) again.
The LCD displays the measured temperature in consideration of the
changed lead resistance.
Ø
Each following time the yellow multi-function pushbutton (5) is briefly
pressed, the display changes between measured temperature with
changed lead resistance and correction value of the lead resistance.
You can exit the function “temperature measurement with changed lead
resistance”.
Set the function selector switch (6) to Hz.

9. Resistance measurement and continuity test

Verify that the device under test is electrically dead. External voltages
would falsify the measured results!

Ω
When measuring small resistance values on the 300
Ω
range, you can
eliminate the resistance of the leads and contact resistance by zero
adjustment.
Ø
Connect the test leads to the meter and join the free ends.
Ø
Briefly press the yellow multi-function pushbutton (5).
The meter acknowledges zero adjustment by a sound signal, the LCD
shows “ 000,00” resp. “0,0000” (+1 digit) and symbol “ZERO” (18) is
displayed. The resistance measured the instant the pushbutton is
pressed is used as reference value (max. 2000 digits). it is
automatically deducted from the values measured thereafter.
You can clear the zero adjustment
à
by pressing the yellow multifunction pushbutton (5) for a long time,
clearance is acknowledged by the buzzer sounding twice,
