Datalogging Sample 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 and 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.
