7.3 Parameter setting notes
a)
TDS Factor (P1):
Users can adjust TDS Factor by experimental data or experience. The
following chart lists some commonly used TDS Factors for reference.
Conductivity and TDS Factor
Conductivity of the solution

0~100
μS/cm
0.60
100~1000
μS/cm
0.71
1~10 mS/cm
0.81
10~100 mS/cm
0.94
b)
P2-Select temperature unit (°C-°F):
In P1 mode, press
to enter P2, press
, °C or °F flickering, press
to
choose °C-°F, press
to confirm parameter selection. Long press
to return
to measurement mode.
c)
Restore to factory default:
Select Yes to restore the calibration to the theoretical values and parameter
setting to original values. When meter’s calibration or measurement performs
abnormally, this function can be adopted so the meter goes back to factory
default setting and then users can conduct calibration or take measurements
again.
