 The three analog channels have identical
characteristics. Each channel can operate in two modes,
Absolute and Ratiometric. The mode of operation is determined
by the probe type selected for that channel. The probe type
is selected using the Channel and Probe Setup Tab of the Logger Control Screen in the
Omnilog Software. Using this software, a different Probe can be selected for each Channel.
Temperature (Thermister) , Pressure and Humidity probes are
typically Ratiometric. Voltage and current inputs are
Absolute.
|
|
|
| Maximum readable input voltage in Ratiometric
mode |
3.6 Volts Nominal (see note) |
| Maximum readable input voltage in Absolute
mode |
2.048Volts |
| Maximum voltage input without damaging logger |
5 Volts |
| Maximum current to be drawn by the combination
of all three probes |
5mA |
| Input Leakage Current |
0.1uA |
|
|
|
Note:The maximum readable voltage in ratiometric mode
should be derived from the logger supply (Pin 1) and will therefore decrease over the life
of the battery to a minimum of 2.7 Volts.

One Fast Pulse Digital Channel |
|
|
To log: |
| Rainfall |
| Wind speed |
| Counter (up to 65535) |
| Flow |
| Frequency (up to 60 kHz) |
|
|
|
The fast pulse input can be used in two modes, Counter or
Frequency.
Counter mode is used for functions such as rainfall.
Frequency Mode is used for wind speed or flow sensors. The mode of operation is determined by the probe type selected for that
channel. The probe type is selected using the Channel and
Probe Setup Tab of the Logger Control Screen in the Omnilog Software.
