Martel Electronics BetaLOG-PI - Manual (Page 5)

the BetaLOG application or the gauge 'CLEAr DATA' function is used
clear the logged data in the gauge, at which time the mode is set to
Demand. In Download mode none of the parameters may be changed
using the gauge menus and the downloaded values are always used
for each new log run. The BetaLOG application may be used to
change the logging parameters between runs without affecting
previously logged data stored in memory. The Download mode data
logging parameters are:
• Interval time selection:
- 1, 2, 5, 10, 30 seconds
- 1, 2, 5, 10, 30 minutes
- 1 hour
• Maximum number of samples to store per run. This may range from
1 to the full capacity of the gauge.
• Log type selection:
- Continuous. This is the most commonly used log type where a
sample is stored at every interval during the run. The sample
value stored is defined by the sample type selection below. The
run can be stopped manually, or stops automatically when the
log memory is full or the maximum number of samples per run is
logged.
- Trip high, where interval samples are stored during the run only
when the sample values exceed a high limit. Sample storage
starts when an interval's sample value becomes greater than the
trip setpoint, and continues at every interval until a subsequent
interval's sample value becomes less than the trip reset. Sample
storage then stops until a sample value again becomes greater
than the trip setpoint. The sample value stored, and used for
comparison, is defined by the sample type selection below. The
run can be stopped manually, or stops automatically when the
log memory is full or the maximum number of samples per run is
logged.
- Trip low, where interval samples are stored during the run only
when the sample values exceed a low limit. Sample storage
starts when an interval's sample value becomes less than the trip
setpoint, and continues at every interval until a subsequent
interval's sample value becomes greater than the trip reset.
Sample storage then stops until a sample value again becomes
less than the trip setpoint. The sample value stored, and used for
comparison, is defined by the sample type selection below. The
run can be stopped manually, or stops automatically when the
log memory is full or the maximum number of samples per run is
logged.
