Interfaces
The connections for the sensor and data cables are located on the
front of the measurement device. The cable connectors and sockets
are colored for easy identification.
To unplug the connector, push the connector sleeve backwards to
release the lock. Only then should you remove the connector from the
device. Never pull directly on the cable!
Analog
The blue channels marked with 'A' and 'B' are used as the:
-
Input for analog signals
- Charging socket for the battery (A or B)
The analog measurement channels are not electrically insulated.
For 2-channel measurement on two machines, check the potential
equalization (VDE 0100) or use electrically insulated sensors.
Digital
The yellow channel is used as the:
-
Input for the digital signal (trigger or rpm sensor)
- Serial interface for data transmission (RS 232)
- Analog output (connection for headphone/oscilloscope)
- Output for stroboscope control (TTL signal)
Permissible range for trigger signals:
-26V ... 0V (negative) or -5V ... +26V (positive).
Switching threshold, positive: max. 2.5V rising
min. 0.6V falling
Switching threshold, negative: min. -8V rising
max. -10V falling
The input signal must not exceed the switching threshold of the
positive
and negative range as otherwise incorrect measurements
can occur.
