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.

Introduction

Thank you for purchasing the HIOKI Model SME-8330 Liquid 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.

Overview

This device is used for liquid sample insulation resistance (volume resistance) measurement and its construction is in accordance with the attached drawing of JIS C-2320 “Electrical insulation oil”. See “Names of Parts”.
This device consists of main and counter electrodes and a protection electrode (guard) which removes leakage current through the insulator to sustain the above electrodes.
As insulators, extremely chemically stable and strong insula-tors (Teflon, KelF, Difron) are used and the electrode surface is nickel-plated in order to increase electrolysis uniformity and chemical strength. Also, the device has a construction that facilitates disassembly and assembly for easy washing, enabling a wide range of sample measurement.
Get 25 cc sample for its measurement.
When its cell constant is approx. 500 cm and Hioki SM-8210 Ultra Megohm Meter is used, up to 1019Ω•cm can be measured.
As for the cell constant, please refer to the inspection sheet.
The operating temperature range is between 0°C and 60°C.

Safety Information

This manual contains information and warnings essential for 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 cautions and warnings.
Warning Indicates that incorrect operation presents a significant hazard that could result in serious injury or death to the user.
Caution Indicates that incorrect operation presents a possibility of injury to the user or damage to the device.
Note 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 the no damage occurred 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 connection lead 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.

Caution

If a measured sample is easily volatilized and/or is easily ignited, explosion and/or fire may result.
Since measuring high-temperature liquid causes the whole device to be hot, be careful not to burn yourself.
To avoid breaking the cables do not bend or pull them.
Do not strike the bottom plate. Applying a load of 20 N (about 2 kgf) or more to the bottom plate could damage the device.

Note
Electrode contamination exerts an influence directly on measuring accuracy. If the device is contaminated, disassemble it for cleaning.

Cleaning procedure

Remove the three screws at the bottom of the inner electrode, then fully clean the insulator between the main electrode and the guard electrode.
For cleaning, a cleaning solvent depending on the contamination is used but in general, avoid the use of an organic cleaning solvent. For hard-to-remove stains, use an industrial-type ethanol (95% concentration).
After cleaning, fully dry the insulator, then assemble the de-vice to measure insulation resistance of the empty electrode.
Overly hasty inner electrode insertion for measurement may cause sample overflow.

If it occurs, immediately wipe the overflow ample off.
A measured sample of high viscosity may heavily contaminate the device and as a result device cleaning becomes difficult.
As device materials described in the outline, chemically stable materials are used. Avoid the use of acid, alkali or halogen compound.
Measured values may vary with measuring voltage, measuring time, sample temperature, etc.
Therefore, it is necessary to ensure that measuring conditions are always constant. In addition it is important that measuring and environmental conditions are clearly recorded together with the measured data.
If a measured sample contains metal particles and sludge, measurement may be disabled.
Therefore, filtering should be considered if the sample contains solids.

Measurement Procedure

Measurement Preparations

Confirm that the electrode is washed clean.
Confirm that a value larger than the insulation resistance of a measured sample is indicated with the insulation resistance measured using an empty electrode.
Actually, if the measured resistance value is 1013Ω, it is necessary that the resistance value measured using an empty electrode be more than 1014Ω. If a measured sample insulation resistance is unknown, clean the device so that the insulation resistance meter used indicates the maximum value ( ).

Measurement procedure

Remove the device tightening ring, then pour a measured sample in the electrode twice or three times for device washing with the measured sample.
Pour an approx. 25 cc sample in to the device then firmly tightening ring.
Connect the device correctly to the Rx terminal on a Hioki insulation resistance meter with a connection lead. When the SM-8200 series is used, always turn the MEA-SURE switch to OFF, prior to device connection. When the SM-8000 series is used, always turn the Charge/Discharge switch to DISCHARGE, prior to device connection.
When the main frame manufactured before the SME-series is used, voltage is applied simultaneously with the connection.
sample volume resistivity becomes as follows:
Volume resistivity =Insulation resistance obtained (Rv) x Cell constant (Ω•cm)

Maintenance and Service

Caution

Use only the specified measurement cable. Using a non-specified cable may result in incorrect measurements due to poor connection or other reasons.

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 ship-ping.
The insulation performance of all of the plastic parts may deteriorate depending on usage environment or use. These parts are not covered under warranty.
