Using MI70 in Recording
Record continuous measurement data and view the recorded data by using
the MI70. This function is found from the menu RECORDING/
VIEWING.
You can switch MI70 off during recording to save battery power. Display
message tells you that recording continues undisturbed even when the
power is off. If the indicator is switched off during recording, the progress
bar is shown on the display every 10 seconds (all the time, if the charger is
connected). This bar shows the amount of recorded data.
Save individual measurement data points with Hold/Save function
(DISPLAY-HOLD/SAVE DISPLAY) and view the saved data from the
RECORDING/VIEWING menu.
CAUTION Do not disconnect the probe when the data recording is on, even if the
indicator is off. This may cause loss of recorded data.
