Datalogging more than one Reading Set per Measurement Session
If the MEM button is pressed more than once during a measurement session, more than one
reading set will be created for that measurement session (one reading set for each MEM
press). This is useful if more than one 'initial reading' is desired for a given measurement
session. The MIN/MAX/AVG values logged in each reading set represent the MIN/MAX/AVG
values recorded between the MEM presses. See the time‐line example below:
MEAS‐01: MEASURE button is pressed (measurement session begins)
A: No logging during this period
MEM01: MEM button is pressed momentarily, logging begins into location 'Data 0'
B: Reading set 'Data 0' logs initial reading and MAX/MIN/AVG readings
MEM02: MEM pressed again, previous log (data 0) ends and new log (data 1) begins
C: Reading set 'Data 1' logs initial reading and MAX/MIN/AVG readings for this time period
MEAS‐02: MEASURE button is released (measurement session and logging ends)
