VOLTCRAFT MT-52 Bedienungsanleitung Seite 47

The long measuring time due to the build may cause deviations between the displayed and the "actual"
temperature and humidity in case of short measuring durations� Therefore, this product must not be used
for very exact measurements (e�g� quality-control climate monitoring, etc�)�
11.12 Temperature measurement with contact sensor
Contact measurement is only permissible with powered-
down objects� Danger of electric shock!
Due to its build, the included wire sensor is only designed
for a measuring range between -20 and +230 °C� With
optional K-type thermal sensors, the complete measuring
range of the DMM can be used�
Proceed as follows for the measurement:
1
1� Switch on the DMM and select the measuring range according to
desired resolution: "1 °C" or "0�1 C"�
2� Connect the K-type measuring adapter to the "V" (+) and "COM" (-)
in the correct polarity�
3� Connect the sensor to the measuring adapter in the correct polarity�
The polarity is marked on the plug�
4� guide the measuring prod to the object to be measured� The meas-
uredvalue is shown in the main display in °C�
5� Switch off DMM after measuring�
The measured temperature must only be applied to the measuring prod� The measuring device must be
in the specified environment to prevent measuring errors.
11.13 Noise level measurement
The sound level measurement is used as an orientation measurement to identify sources of sound� Evaluating meas-
urement for documentation, etc� is not possible� The sound level is measured linearly (characteristic "C"), i�e� all
sounds (low and high ones) are assessed equally� Thus, you will receive frequency-independent measured values
that make comparison easier�
The measuring aperture for sound is at the upper left (16)� During measurement, the measuring device should be
aligned at a right angle to the sound source�
Always wear hearing protection when working in loud environments to prevent damage to your hearing�
