Temperature Measuring; M) 3-Phase Rotating Direction Display "Motor - VOLTCRAFT VC-450 E Bedienungsanleitung

l) Temperature measuring
During temperature measurement, only the temperature sensor must be subject to the temperature
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 measurement
range (-40 to +1000 °C) of the multimeter, optional type K
thermal sensors are available. The enclosed adapter plug is
required to connect type-K sensors with miniature plugs.
Any type K thermal sensor may be used for temperature
measurement. The temperature values can be displayed in
°C or °F.
For measuring temperatures, proceed as follows:
- Turn the DMM on and select measuring function "°C°F".
The display shows the unit °C for temperature measure-
ment.
- Connect the enclosed type-K-measuring adapter (O) to the
V- and COM-measuring jacks in the correct polarity. The
adapter only fits onto the meter in the proper direction and
will cover the current measuring jacks for safety.
- Plug the enclosed temperature sensor into the measur-
ing adapter in the correct polarity. The two contacts of the
thermocouple are differently wide, to prevent wrong con-
nection.
- The display shows the temperature value in °C.
- The "SELECT" button 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 measurement range
has been exceeded or the sensor is interrupted.
- After measuring, remove the sensor and turn off the DMM.

m) 3-Phase rotating direction display "Motor"

The DMM may identify the rotating direction in a 3-phase current network via the measuring function "Motor". Only 2
measuring lines are needed to display the rotating direction. During identification, the outer conductors L1, L2 and L3
must be scanned in sequence. The DMM recognises the phase offset and shows the rotating direction (rotating field)
with an arrow subsequently.
The 3-phase rotating direction display can be chosen only in the AC-V-range.
