Auto leads resistance calibration
When entering the 50
Ω
range
manually
by
RANGE
button for high precision low
resistance measurement, this feature will prompt you to short the inputs for calibration.
The display shows “Shrt”. Simply short the leads for about 3 seconds until the display
shows zero, then the resistance in the leads and in the internal protection circuitry of
the meter is compensated automatically. The compensation value can be as much as
5
Ω
. If you need a compensation value that is higher than that, Relative mode is
recommended.
The shortcut is to short the test leads in auto-ranging resistance mode until the meter
enters the lowest 50
Ω
range automatically, press the
RANGE
button momentarily to
get the “Shrt” prompt, then wait about 3 more seconds until the display shows zero.
Note: The calibration stays until you change ranges, functions, or go back to auto-
ranging mode.
