Introduction

Thank you for purchasing the HIOKI Model SME-8310 Plate Sample Electrode. To obtain maximum performance from the device, please read this manual first, and keep it handy for future reference.
Inspection
When you receive the device, inspect it carefully to ensure that no damage occurred during shipping. If damage is evident, or if it fails to operate according to the specifications, contact your dealer or Hioki representative.

Safety Information

This manual contains information and warnings essential for the safe operation of the device and for maintaining it in safe operating condition.
Before using it, be sure to carefully read the following safety precautions.

Safety Symbol

In the manual, the symbol indicates particularly important information that the user should read before using the device.
The following symbols in this manual indicate the relative importance of caution and warnings.
Indicates that incorrect operation presents a significant hazard that could result in serious injury or death to the user.
Indicates advisory items related to performance or correct operation of the device.

Operating Precautions

Follow these precautions to ensure safe operation and to obtain the full benefits of the various functions.
Preliminary Checks
Before using the device the first time, verify that it operates normally to ensure that no damage occurs during storage or shipping. If you find any damage, contact your dealer or Hioki representative.

WARNING

Before using the device, make sure that the insulation on the test leads is undamaged and that no bare conductors are improperly exposed. Using the device in such conditions could cause an electric shock, so contact your dealer or Hioki representative for repair.

NOTE

Full attention must be exercised in electrode handling including sample pre-treatment.
Avoid conducting measurement immediately on a sample stored at a cold location and then brought into the measuring room at ambient temperature. Also, holding a sample with bare hands or storing many samples by stacking may exert an influence on the measurement.
Some samples may generate a potential which causes reverse indicator deflection.
There is no one rule on how to handle each sample, but it is always best to select the measuring instruments, measuring conditions, measuring methods, and measuring environment for comparison of measured data.

The details of consideration are described in the following.

Overview

This is an electrode to measure sample surface resistance and volume resistance with a sample accommodated in the electrode.
The main electrode dia. is 50 mm and the inner and outer ring electrode dias. are 70 mm and 80 mm, respectively.
Measurable sample size is up to 100 mm x 100 mm and sample thickness is up to 8 mm.
The operating temperature range is between 0°C and 40°C.

Measurement Procedure

To best display the function of this device, it is recommended that the SM-8200 Series Super Megohm Meter be used.

NOTE

If the cover on the device is opened with the meter set to MEASURE, the measuring voltage is turned OFF to avoid electric shock. However, the indication on the indicator may change depending on the SM-8200 Series meter measuring range, because the main electrode is not disconnected even in the MEASURE position.

Confirm that the SM-8200 Series meter is set to DISCHARGE, then connect the electrode to the meter. For best results, provide HV-EN (external control of measuring power supply) when using the SM-8200 Series meter. When HV-EN is provided, the measuring voltage can be controlled by cover opening/closing.
Open the cover. It can be opened when the handle is lifted by pressing the white button and center front. Fully open the cover until it is stopped.
Load a sample at the center of the device and then close the cover. When closing, first hold the handle with the thumb and the index and middle fingers and lower the cover until the male lock metal engages the female lock metal, and then further lower the cover while pressing the white button with the thumb, remove the thumb from the white button. Measurable sample size is up to 100 mm x 100 mm.
Turn the FUNCTION switch on the right side of this device to Rs for surface resistance measurement, and to Rv for volume resistance measurement. Turn the same switch to RESET during sample replacement. (See “Names of Parts”.)
Conduct measurement under the HIOKI SM- 8200 Series Super Megohm Meter instruction manual.

Volume Resistivity and Surface Resistivity

Values obtained by multiplying the measured results of volume resistance and surface resistance by cell constant are called volume resistivity (ρ) and surface resistivity (σ).

In Equations (2) and (4), K1 and K2 are called cell constants.
By substituting the actual values for Equations (1) and (3), the device cell constant can be obtained.
Equations (5) and (6) are used for the actual measured result.

Example of electrodes

	Volume resistivity	Surface resistivity
A	Main electrode	Main electrode
B	Guard electrode	Counter electrode
C	Counter electrode	Guard electrode

Maintenance and Service

It is recommended to clean the surface of electrode by blowing dry air. Clean the surface of electrode and also the dust between electrodes.
If the electrode is obviously dirty, please clean it with industrial ethanol (use a concentration of at least 95%). But diminish the liquid volume as possible and clean it not to diffuse the stain.
To clean the device, wipe it gently with a soft cloth moistened with water or mild detergent. Never use solvents such as benzene, acetone, ether, ketones, thinners or gasoline, as they can deform and discolor the case.
If the device seems to be malfunctioning, contact your dealer or Hioki representative.
Pack the device so that it will not sustain damage during shipping, and include a description of existing damage. We cannot accept responsibility for damage incurred during shipping.
The conductive rubber parts may deteriorate due to usage environment or use. These, which are consumable, are not covered under warranty.

Warranty

Warranty malfunctions occurring under conditions of normal use in conformity with the Instruction Manual and Product Precautionary Markings will be repaired free of charge. This warranty is valid for a period of one (1) year from the date of purchase.
Please contact the distributor from which you purchased the product for further information on warranty provisions.
