k) Room Temperature and Humidity Measurement
The DMM enables measuring the room temperature and relative humidity via firmly installed
sensors. The two measured values are permanently displayed in the upper display area in
measuring operation.
The sensors are located inside the device and react to changes of the measured value
with delays. Wait for at least 30 minutes until the device has adjusted to the ambience
conditions. We recommend waiting for approx. 2 hours to ensure precise measured
values.
Proceed as follows for the measurement:
• The measuring leads are not required.
• Turn on the DMM and select any measuring
function.
• In the upper left, the display shows the relative
humidity in “%RH” and in the upper right the
room temperature in “°C”.
• Wait until the displayed value has stabilised. This
may take up to 2 hours.
• Switch off DMM after measuring.
The long measuring time due to the build may cause deviations between the dis-
played and the “actual” temperature and humidity in case of short measuring dura-
tions. Therefore, this product must not be used for very exact measurements (e.g.
quality-control climate monitoring, etc.).
