Operating Manual
Voltage DVM [mV].
The power supply for additional transmitters needs to be provided externally.
Important:
Connecting voltages higher than 10 Volts will damage the device.
7.5.9 Strain gauge – sensors (YL-M32 only)
The YL-M32 logger can measure two strain gauges. It is designed for full resistance
bridges at 60-700 Ohms.
Simply use YY-CS cables to connect the sensor to the logger.
This connection can be configured in
LoggerSetup/SensorSlot
- SlotMode:
DMS
.
Usually complete Strain gauge bridges are supplied calibrated. In the calibration
certificate the bridge rated output
will be listed. With these specifications the
bridge rated output
is converted as followed:

YoyoView plus has an integrated formula editor, which allows you to enter a formula as
described above to calculate Forces/tensions from the mV reading.
