Datalogging Sampling Rate
Press the TIMER key momentarily to display the datalogger's sampling
rate (recording interval). The factory default interval is 0.05 seconds,
meaning that a reading will be logged every 5 hundredths of a second.
Press the UP or DOWN arrow key momentarily to select an alternate
sampling interval. Choose from 0.05 up to 480 seconds. Note that the
fastest sampling interval for Temperature and Resistance readings is 0.2
seconds; For Frequency it is 0.4 seconds; and for Capacitance it is 1
second. Press the TIMER key again to confirm the new setting.
The Sampling Rate cannot be changed while the meter is datalogging.
When a Sampling Rate of 20 seconds or longer is selected, the meter
enters a standby state between readings (to conserve battery life). While
in stand-by, the bargraph will continue to operate. To wake-up meter
from a stand-by state in order to view a real-time measurement, press
the SELECT key momentarily.
