11. Temperature measurement
The DELTA SOLAR allows you to measure temperature with Pt100 and Pt1000
temperature sensors in the range from-200(-100) C...+850 C.
Set the function selectors witch(6) to " Ω ."
Connect the sensor to the two terminals.
Briefly press the yellow multifunction push button(5).
The clamp meter switches to temperature measurement, it
automatically detects the connected sensor(Pt100 to Pt1000) and
shows the measured temperature in
0
C on the digital display.
Notes:
This measurement automatically considers the lead resistance of
temperature sensors which are available as accessory.
It is not possible to switch over to temperature measurement when the
30
Ω resistance range is selected.
Sensor lead resistance upto 50
Ω
Lead resistance of sensors having a value differing from tha t of company sensors
can be considered upto a value of 50
Ω
as follows:
Briefly press the yellow multi-function push button(5) again.
The LCD now displays the resistance value which the clamp meter
automatically considers after selecting the temperature measuring range.
We can recognise that this is the resistance correction value on the
temperature measuring range. The “
0
C ” character is simultaneously
shown on the display.
You can set the lead resistance correction value as follows:
Press the HOLD push button(3) to increment the value, or the AUTO/MAN
push button(4) to decrement the value. Each time the push button is briefly
pressed, the value changes by one digit.
Briefly press the yellow multi-function push button (5) again.
The LCD displays the measured temperature.The flashing decimal point shows
you that we have entered a correction value for the lead resistance.
The correction value is retained as long as clamp meter is switched on.
Note:
Each time the yellow multi-function push button(5) is briefly pressed, the
display changes between measured temperature and correction value of
the lead resistance.
We can exit the temperature measurement function
by pressing the yellow multi-functions button(5) longer, this is confirmed by the
two sound signals.
by changing the function selector switch.
For the lead resistance, the actual value measured on the clamp meter should
be taken as correction value and not any specified value.
12. Capacitance measurement
Verify that the device under test is electrically dead. External voltages would
falsify the measured results.
Set the function selector switch (6) to 'F'.
Connect the (discharged!) device under test to the" "and "F" socket via test lead.
Notes:
Connect polarized capacitors with the"_"pole to the" "socket.
Resistors and semiconductor junction in parallel with the capacitor falsify the
measured results!
