5.3 Data logger function

The data logger function allows the automatic and manual storage of series of measurements (Funktion
Ω/ Ω , mA/ A) with a predefined measuring interval (sampling rate) and up to 116 measured values. The
measuring interval can be set from 1 s to 255 s. The measured values can be read out later by means of
the display 4 .
5.3.1 Setting the sampling rate
Press the FUNC key 9 several times until the "SEC" symbol appears on the secondary display A. The
digital display B shows the sampling rate in seconds. Use the ▼ key 6 und the ▲ key 8 to set the sam-
pling rate from 1 s to 255 s. Press and hold the keys to accelerate the setting process. Then, press the
FUNC key 9 several times until the symbols on the secondary display A disappear.
Note:
To store only a single measured value, select a sampling rate of 0 s. Each time the REC key 5 is pressed,
another measured value is stored in the internal memory and the storage location number is briefly shown
on the secondary display A.
5.3.2 Starting and stopping the data logger
Press the REC key 5 to start the data logger. At the same time, the REC symbol J appears on the digital
display 4 . The measured values are stored in the internal memory taking into account the sampling rate set.
The data logger can be stopped by pressing the REC key 5 and stops automatically as soon as the meas-
ured value memory is full. The REC icon J on the digital display 4 disappears.
5.3.3 Calling measured values
Press the FUNC key 9 several times until the "NO." symbol I appears on the digital display 4 . By press-
ing the ▼ key 6 and the ▲ key 8 , the storage location number is selected via the secondary display A
and the corresponding measured value is shown on the digital display B.
