Preparation

Preparation of the apparatus

① Open the lid, and wipe the electrodes for

cleaning.

How to wipe the electrodes

Please wipe the electrodes gently with a cotton
stick soaked in ethanol.

② Put the batteries in.

③ Otherwise, connect the AC adapter.

 Up to 6 elements are registerable before the measurement,

shown at right photo.

 The registered elements are shown at right photo.
 The registered elements are variable.
 If you change the registered elements , please refer to the

” User’s manual / about configuration”

Putting in liquid sample

① Prepare a dedicated container (LepiCuve) in

advance.

②. Take a sample with micropipette. 30-40 ul (one

drop is required for one measurement.

③Put a sample into the one side of LepiCuve.

④Place a syringe softly on the one hole filled a
liquid sample. Fix the syringe by one hand, and push
a piston carefully. Push out about a half to the
other side using a syringe, looking for moving of a
liquid sample.

⑤Confirm for the both hole of LepiCuve filled with a
liquid sample.

Measurement

Operation of the apparatus

①Turn a power switch on.

②Please wait during the message is shown

as the left photo.

③ Confirm whether measurement mode
may be appropriate.

Please change the measurement
mode, if it is not appropriate.
(referring to the page○)

The measured elements are shown
on the display. Up to 4 sets of 6
elements are selectable in advance.

④Open a lid of the apparatus.

⑤Put LepiCuve in the pit of the apparatus.

⑥Close the lid softly.

If the other messages are shown on a display,
Please refer to“Troubleshooting”( page,○).

⑦Make sure that “Resistance ＯＫ” is shown.

１．The measurements cannot be done

because conducting is too low.

２．The measurements cannot be done

because resistance is too low

Please refer to “Troubleshooting Tips”, if
the message is shown as left.

⑧Press a start button, then a measurement

starts.

After Measurements

①Open a lid, and put off LepiCuve.

②Wipe electrodes softly.

③If you measure some

another samples, please
back to the step
“measurement” （P.8）
