b. Set Average
This is the Set Average Menu. This is where you can make changes to the averaging period. Readings are updated at a rate of one
per second. A higher averaging time will give smoother curves to the graphical display and to recording devices and helps “wash
out” anomalies. Always use the X1 setting when taking grab sample readings. Suppression or “Holding” the least significant digits
to zero may be set here. The X1 setting is automatically selected while in the calibration menu.
Selection Options:
F1: Selects each reading (one second)
F2: Selects Averaging of the last sixteen readings (16 seconds)
F3: Selects Averaging of the last forty-eight readings (48 seconds)
F4: Selects Averaging of the last ninety-six readings (96 seconds)
F5: Selects between 1 digit, 2 digits & none of the least significant digit suppression
