PCAL
(applicable only to the MilliVolt sensor type) This pressure calibration value
represents the number of millivolts at full range. This value is unique for each
sensor, and sometimes is referred to as Full Scale Detection (FSD).
Custom Offset
(applicable only when measuring pressure, height, or depth) This field
indicates the offset added to all readings. For example, enter the appropriate
value to add to all pressure values to compensate for ground level. To remove
an amount from every reading, simply enter the value as negative.
Electrical Range
(applicable only to voltage or current data types) These fields represent the
electrical range corresponding to the voltage or current, as applicable. Enter
or use the up/down arrows to designate a range up to 20mA for current.
Select 0-2V, 0-5V, and 0-10V for voltage.
Physical Range
(applicable only to the current or voltage sensor type) These fields represent
the range of the sensor input corresponding to the voltage. For example,
consider an input of 4-20mA involving a temperature sensor where 4 mA
represents 0 degrees and 20 mA represents 100 degrees. This would require
entering the values 0 and 100 in the Physical Range fields. Enter the values
manually or use the up/down arrows.
Logging Interval
This drop-down list includes the options for setting the measurement interval
at which to log data on this channel. Options available range from 1 second to
24 hours. The data logged on this channel represents averaged data (based on
the number of samples taken). XiLog+ records the averaged data and daily
minimum and maximum values for the channel.
