h) Capacity Measuring

Make sure that all circuit parts, circuits and components and other objects of measurement are
disconnected from the voltage and discharged.
Always observe polarity with electrolyte capacitors.
- Switch on the DMM and select measuring range
- Press button "SELECT" (9) 3x to switch measurement functions. The display
shows the unit "nF" for capacity measurement. Pressing this button again
takes you to the next measuring function, etc.
- Plug the red measuring line into the Ω measuring jack (7) and the black
measuring line into the COM measuring jack (8).
Due to the sensitive measuring input, the display may show a value if the
measuring lines are "open". By pressing the button "REL", the display is
set to "0". The Auto range function remains active.
- Now connect the two measuring prods (red = plus/black = minus) with the object to be measured (capacitator).
After a short time the display shows the capacity. Wait until the displayed value has stabilised. This may take a few
seconds for capacities of >40 µF.
- If "OL" (overload) appears on the display, you have exceeded the measuring range.
- Remove the measuring lines from the object to be measured after completion of the measurement and switch off
the DMM.
i) Temperature Measurement
During temperature measurement, only the temperature sensor must be subject to the tem-
perature to be measured. The meter working temperature must not be undercut or exceeded.
Otherwise, there may be measuring errors.
The contact temperature sensor must only be used at voltage-free surfaces.
The meter contains a wire sensor that can measure up to temperatures of -40 to +230 °C. To use the full measuring
range (-40 to +1000 °C) of the multimeter, optional type-K thermo sensors are available. To connect type-K sensors
with miniature plugs, an optional adapter plug is required.
Any type K thermo sensor may be used for temperature measurement. The temperature values can be displayed in
°C or °F.
For measuring temperatures, proceed as follows:
- Switch on the DMM and select measuring range "°C". The temperature meas-
urement symbols now appear in the display.
- Plug the enclosed temperature sensor into the V measuring jack (9) in the
correct polarity with the plus pole and into the COM measuring jack (8) with the
minus pole.
- The display shows the temperature value in °C.
- The "SELECT" button (9) can be used to switch the unit from °C to °F. Every
time you push the button, you switch the unit.
- If "OL" appears on the display, the measuring range has been exceeded or the sensor is interrupted.
