value DREF on primary display and the "Δ" segment will be blinking.
The percentage range is -99.9%~99.9%. When the relative value
is larger than double of reference value (DREF), the "OL%"
indication will be shown on the secondary display. Press and hold
downthe button for 2 seconds to exit the relative mode.
In order to improve the accuracy of high/low impedance, it is
recommended to do OPEN/SHORT calibration mode before
measurement. Press and hold down the button for 2 seconds
to enter calibration mode. The calibration procedure: OPEN
ready OPEN calibration(30s) SHORT ready
SHORT calibration(30s) . During open or short calibration
