Page 14: Operating Precautions
Before using the instrument for the first time, verify that it operates normally to ensure that no damage occurred during storage or shipping. If you find any damage, contact your authorized Hioki distributor or reseller. Instrument Installation Installing the instrument in inappropriate locations may cause a malfunction of instru- ment or may give rise to an accident.
Page 15 Operating Precautions Handling the Instrument To avoid damage to the instrument, protect it from physical shock when transporting and handling. Be especially careful to avoid physical shock from dropping. This instrument may cause interference if used in residential areas. Such use must be avoided unless the user takes special measures to reduce electromagnetic emissions to pre- vent interference to the reception of radio and television broadcasts.

Page 210 Figure 4. Ideal Four-Terminal Method H CUR , (L CUR ) (Current generation) To facilitate measurement, the tips of the Model Hioki 9140-10 4-Terminal Probe are jagged. As shown in Fig.5 (enlarged view of probe tip contact area), the measurement current flows from multiple points, and the voltages are detected at multiple points.
Page 211 Try to measure after the temperature of the measured object becomes close to that of room temperature. Use an instrument with a temperature-compen- sation function such as the Hioki RM3544, RM3545 and RM3548 to minimize temperature dependence of copper etc.
Page 212 Appendix 3 Unstable Measurement Values (6) The Sample Becomes Warm The maximum applied power to a measuring object by this instrument is determined as follows. The resistance of samples with small thermal capacity can change due to heating. In such cases, set the low- power resistance measurement to ON.
Page 213 To obtain stability in a constant-current source with a large inductance, response time is sacrificed. If you find that resistance values are scattered when measuring large transformers or motors, please consider the above or contact your local Hioki distributor for further assistance.

Page 222 Appendix 9 Zero Adjustment Appendix 9 Zero Adjustment Zero adjustment is a function which adjusts the zero point by deducting the residual value obtained during 0 Ω measurement. For this reason, zero adjustment must be performed when the connection is made to 0 Ω. However, connecting a sample with no resistance is difficult and therefore is not practical.
Page 223 Appendix 9 Zero Adjustment To perform zero adjustment appropriately Table 1 shows the correct and incorrect connections. The resistances in the figure indicate lead resistances; there will be no problem if they are less than a few Ω respectively. As in (a), when H and L , and H and L...
Page 224 Appendix 9 Zero Adjustment To perform zero adjustment using a probe When you actually perform zero adjustment using a probe, you may unexpectedly create the connection shown in Table 1 (b). Therefore, when performing zero adjustment, you need to pay sufficient attention to the connection state of each terminal. 9287-10 Clip Type Lead Here, is used as an example for the explaining the connection.
Page 225 Appendix 9 Zero Adjustment To perform zero adjustment using 9454 Zero Adjustment Board When performing zero adjustment, you cannot use a metal board or similar object to replace 9454 Zero Adjustment Board. 9454 Zero Adjustment Board is not just a metal board. Its structure consists of two metal boards screwed together at one point.
