mode.
After setting a value, in soil resistivity testing mode, press the
“START” button to start testing, and countdown display testing process,
stable soil resistivity value is shown when finish testing.
As shown below, the measured soil resistivity is 53.38Ωm, already
stored 157 sets of data. Press “SET” button, the earth resistance rC of
auxiliary current electrode C(H) and earth resistance rP of auxiliary
voltage electrode P(S) will be displayed, and then automatically return
display of measured soil resistivity ρ.
9．Backlight Control
After startup, press button to turn on or off backlight. The
backlight function is suitable to dark spot, power consumption of backlight
is about 25mA. It will default backlight turn-off for each startup.
10．Alarm Settings
After startup, rotate FUNCTION rotary switch to select function,
press button for a brief time to open or shut off alarm function,
press button for a long time (about 3 seconds) to enter alarm critical
value settings, press or to change current digital, press
button to move cursor and then press button to store and exit.
When measurement value is larger than alarm critical settings value and
it has opened alarm function, the tester will flash and display icon
and give out “toot-toot-toot--”alarming sound.
11．Data Lock/Storage
In test mode, press button for a brief time to lock current
displayed data, showing , icon and automatically store with
serial numbers. If storage is full, the tester will display icon, and
then press button to remove lock.
As shown in the left figure below: the lock measurement data of soil
resistivity is 53.38Ωm, as the 28th group of data storage.
