Configuring Warm Up Time
Note: This section only applies to Veriteq VL-4000 and SP-4000 data loggers.
Some VL-4000 and SP-4000 data loggers have the ability to switch power from
an external battery onto a transducer using the Warmup Time feature, also
known as the XPS excitation control switch. This is useful for conserving pow-
er when an external transducer is being powered from an external battery.
Set transducer warm up time to a number of minutes or seconds before data is
recorded by the data logger. To set when the data logger will record data, see
Setting the Data Logger Sample Timing on page 29.
To configure transducer warmup time:
1. Choose Logger>Setup.
2. From the row for the channel you want to set up the warm up time for, click
Setup.
3. From the Setup Channel screen, click Warmup Time.
4. From the Warmup Time screen, select the Timer radio button.
You can also set up warmup time from the Logger Setup window.
