NOTICE
The use of the measuring technology menu requires the optionally available measurement
module (MT 77).
Select measured variables and channels here. Then you can perform various measurements.
Measurement technology is a digital signal acquisition and output. This means that the voltage signal is detected and
saved within a few microseconds. These registered measured values are depicted as continuous signal curve on the
screen in real time.
Just perform measurements under >Measurements< .
Use the measurements function for measuring and/or depicting the following measured variables:
• Voltage
• Current (with amp clamp)
• Resistance
Current measurements are allowed exclusively with the clamp meter from Hella Gutmann. Depending on the required
measurement, different clamps are to be used.
A progress bar in the top toolbar indicates the remaining free storage capacity reserved for that in the diagnostic
device.
Use >Loading measurement< to call up registered and saved measurements.
Use >Delete all measurements< to delete already registered and saved measurements.
CAUTION
