• When " 0.0 µS" stops blinking, the cali-
bration can be confirmed. Press the CFM
key to confirm the offset value.
• If the input reading is out of the offset
range, " E0 " as error message will appear
on the secondary display . Press the CAL
key to re-calibrate the value.
• If everything is satisfac-
tory the LCD will blink
"
84.0 µS", expecting
the next calibration so-
lution (HI7033 or
HI8033).
• Fill a beaker with HI7033
or HI 8033 conductivity
calibration solution.
• Immerse the probe into
the calibration solution.
The level of solution must be higher than
the holes on the PVC sleeve. Tap the
probe repeatedly on the bottom of the
beaker and stir it to ensure that no air
bubbles are trapped inside the sleeve.
• When the " 84.0 µS" stops blinking, indi-
cating that the measurement has stabi-
lized, press the CFM key again to confirm
the second point calibration.
