Temperature Measuring - VOLTCRAFT VC650BT Bedienungsanleitung

Temperature measuring

During temperature measurement, only the temperature sensor must be subject to
the 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.
Any K-type thermo sensor may be used for measuring temperatures. The temperature can be displayed
in °C or °F. Optional sensors can be used for the complete measuring range (-40 to +1000 °C).
For measuring temperatures, proceed as follows:
1. Switch on the DMM and select measuring range "mV
switch the measurement function to °C. Pressing this button again to switch the measuring unit to ºF.
2. Plug the K type thermocouple into the
with the plus pole and into the COM measuring jack (18) with the minus pole. If necessary, use
suitable K type plug-in adapters.
3. The main display indicates the temperature value in °C or °F according to the setting via the
SHIFT / SLEEP button (16).
4. When "OL" is displayed the measuring range has been exceeded.
5. After measuring, remove the sensor and turn off the DMM.
When the measuring input is bridged (sockets: °C – COM) the DMM device temperature is indicated.
Due to the closed casing, the temperature is only slowly adapted to the ambience temperature.
1 kHz low-pass fi lter alternating voltage measurement
Never use the low-pass fi lter option to test for presence of dangerous voltages!
The present voltages may be higher than indicated.
Always perform voltage measurement without the fi lter fi rst to recolonise any
possible dangerous voltages.
The DMM is equipped with an alternating current low-pass fi lter. This is an alternating voltage
measurement routed through a low-pass fi lter that blocks undesired voltages exceeding 1 kHz.
Proceed as follows for AC voltage measurement with the low-pass fi lter:
1. Switch on the DMM and select measuring range "V ~". Press the SHIFT / SLEEP button (16) to
switch to .
2. Plug the red measuring lead into the
measuring lead into the COM measuring socket (18).
3. Now connect the two measuring leads to the object to be measured (generator, circuit, etc.). The
measured value is indicated on the display.
4. After measuring, remove the measuring leads from the measured object and turn off the DMM.
