USB-5100 Series Software Help Working with USB-5100 Series Data Loggers
 Click the
Alarms button to set an alarm for this logger. Note that the Logging Mode must be set to Normal
or Statistics to configure an alarm. For thermocouple loggers, alarms can only be configured on
thermocouple channels; they are not available on the internal 10 K thermistor (temperature) channel.
 Click the
Filters button to create additional filtered series for any of the configured channels. The filtered
series is automatically calculated when you read out the logger and plot the data.
 You can record the logger battery voltage at each sample time; this is the last channel in the sensors list.
Like the other data channels, logging the internal battery channel consumes some of the logger memory.
Unless you suspect abnormal battery performance, you do not need to log the battery voltage. You can also
hide the battery channel with Series preferences (
File»Preferences»Display»Series ).
 Although it is possible to set up more than one scaling value for each sensor, only the first scaling value for
that sensor will be used.
 Labels do not apply to all calculated or derived channels, such as filtered series channels.
Deployment

Logging Interval: Select how often the logger records data. You can choose either one of the preset
logging intervals or specify a custom logging interval. The minimum logging interval is one second and the
maximum interval is a
Custom interval of 18 hours, 12 minutes, and 15 seconds. The shorter the logging
interval, the more quickly memory fills and battery power is consumed.

Logging Mode: Select Normal , Burst Logging , or Statistics logging mode.
o Normal: Configures the logger to collect data at the selected logging interval.
o Burst Logging: Configures the logger to use a different logging interval when specific conditions are
met. Burst logging is not available for the internal temperature channel (if available).
The Burst Logging interval must be less than the Logging Interval.
o Statistics: Configures the logger to calculate maximum, minimum, average, and standard deviation
during logging for all enabled sensors except battery voltage. The more statistics you record, the
shorter the logger duration and the more memory is required. Once you launch the logger, the selected
statistics are displayed on the logger LCD. Statistics logging is not available for the internal
temperature channel.
If you select Burst or Statistics logging, an Edit button displays next to Logging Mode in the Launch
Logger dialog box. Click this button to make additional changes as necessary.
If you select Normal or Statistics logging, you can click Alarms to set an alarm for the logger.
Click Filters to create additional filtered series for any of the channels you configured. The filtered series is
automatically calculated when you read out the logger and plot the data.
You can record the logger battery voltage for each sample. Logging the internal battery channel consumes
logger memory. Unless you suspect abnormal battery performance, you do not need to log the battery
voltage. The logger records a bad battery event even if it is not logging the battery channel. You can also
hide the battery channel with Series preferences (select
File»Preferences»Display»Series ).

Logging Duration: Calculates the approximate time it takes to fill the logger memory based on the logging
interval, logging mode, and sensors currently selected. This is an estimate only – battery life and other
factors also affect the duration.

Start Logging: Select one of the following options to launch the logger:
o Now: Logging begins as soon as you click Start in the Launch Logger dialog box.
o At Interval: Logging begins at an exact interval (for example 9:00:00 rather than 8:47:00 when you
choose a one-hour logging interval). The exact start time depends on the logging interval you choose.
o On Date/Time: Logging begin at a date and time you enter, up to approximately six months from the
present. The LCD screen counts down to that start date/time and then logging begins.
o Push Button: Logging starts when you press the Start/Stop button on the logger and hold it down for
at least three seconds. The LCD screen on the logger displays Start until you press the button.

Stop Logging: Select one of the following options to stop the logger:
o When memory fills: The logger stops recording data once the memory is full.
o Never (wrapping): The logger records data continuously until either the logger battery runs out or you
stop it. When the logger memory is full, the newest data overwrites the oldest data. A wrap indicator
icon displays on the logger LCD screen.
