Measure Modes

Select CONTINUOUS or SINGLE under MEASURE MODES in the OPTIONS Menu
using the arrow buttons and the SELECT soft-key.
In the CONTINUOUS measurement mode the meter displays a running average of
readings as they are taken. Note that the audible measurement 'beep' is not active in
this mode.
In the SINGLE measurement mode measurements are taken one at a time. Single
mode measurement readings are accompanied by an audible tone.
b.

Working Modes

Select DIRECT or GROUP 1, 2, 3, or 4 under WORKING MODES in the OPTIONS
Menu using the arrow buttons and the SELECT soft-key.
In DIRECT mode, individual readings are logged to memory. When power is switched
off or if the meter is switched to GROUP mode, all DIRECT readings will be cleared.
However, the statistical analysis data will remain. The statistical analysis utility can
evaluate up to 80 readings. When the memory is filled, new readings will replace old
readings. Lastly, this mode has its own calibration and alarm limit values.
In GROUP mode each group memory can store a maximum of 80 readings and 5
statistical values. Calibration and alarm limit values can be individually set and stored
for each group. When the memory is filled, measurements will continue to be taken but
readings will no longer log (previously logged readings are not affected); in addition,
statistical data will no longer update. If desired, the group data, statistical values,
calibration data, and alarm limit values can be deleted using the programming menu.
