 Freight Mode 
Selecting this mode prevents the modem from powering up so that the logger 
cannot transmit, even when the logger has been programmed to transmit (e.g., 
because of an alarm). Select this option when air freighting a logger, even if 
the SIM card has been removed. ADS ships all loggers transported by air in 
this mode. 
Read Current Values 
Selecting this checkbox displays the current values from the attached logger in 
the Digital, Analog, Battery Voltage/External Power Voltage, and GSM 
Signal Strength fields, as applicable. PrimeWorks will request data from 
the logger every second. Pressure and other analog data update at this 
interval, but flow values require up to 1 minute to update based on the sample 
rate programmed into the logger. 
Digital/Analog 
These fields display the current value and units for each channel. The number 
of values displayed varies based on the logger features and programming. If 
the XiLog+ is not logging data on a channel, the corresponding field will not 
display a reading. A channel that is not logging data may indicate the channel 
has not been enabled or the end date and time designated for logging data has 
passed. 
AutoZero Button 
Clicking on this button removes the current offset and forces the analog 
channel to read zero. This button is available only when the XiLog+ is 
logging pressure, depth, or height on an analog channel. 
Note: Use this option only with the transducer open to atmospheric 
pressure. This new offset will apply only to future data. It will not be 
applied to previously recorded data. 
Battery Voltage 
This field displays the current internal battery voltage (nominally 7.2V). If it 
reads low and the battery requires replacement, PrimeWorks will display a 
warning once the logger is connected to the computer.
