Operating Manual
7.5.10 Lowest-voltage measurement (YL-M32 only)
The YL-M32 can measure very low voltage signals for example in the range of +/-5mV
with a resolution as low as 0,15µV.
This connection can be configured in
LoggerSetup/SensorSlot
- SlotMode:
High-Impedance.
7.5.11 Voltage - GND reference signals (YL-M32/-M90, max 1V)
In order to measure low voltage levels < 1VDC from grounded voltage sources,
connect the YY-CS cable according to the diagram below.
In this mode the logger can perform at an interval of up to 32 Hz.
Measuring ranges 0-10 mV or 0-1000mV are possible. The measuring range 0-10 mV
allows for a resolution of up to 560 nV. The input impedance in this mode is > 2.5
MOhm.
This connection can be configured in
LoggerSetup/SensorSlot
- SlotMode:
Voltage DVM [mV].
Important:
Connecting voltages greater than 1 Volt will damage the device
