5.2.1. Location Number
The location number is used to assign a unique number to a location or area. This
important field is included in sample data records (display, printer and serial output).
5.2.2. Sample Time
The sample time determines the amount of time that counts are accumulated while the
pump is running. The length of the sample is user settable from 1 – 999 seconds.
5.2.3. Hold Time
The Hold time is the time between samples when sampling in Auto mode (continuous).
The Hold time is user settable from 0 – 999 seconds. The pump will remain on during
the hold period if the Hold time is 60 seconds or less. The pump will stop after each
sample, and start a few seconds before the next sample, if the Hold time is greater than
60 seconds. Hold times greater than 60 seconds will increase pump life.
