| Important Notice Regarding the Use of Electronic Non-Contact Meter Relays |
It has been found that extended use of HIOKI’s Electronic Non-Contact Meter Relays (namely Models 2101 and 2102) over many years will cause the sealing compound that provides insulation protection over the level adjustment knob to naturally wear off. Depending on the usage conditions, instrument safety may be compromised.
All new meter relays shipped from May 6, 2003, have been incorporated with new parts to prevent this from occurring. However, for those customers who are currently using meter relays that were shipped before May 2003, we kindly ask that you conduct the following safety inspections to ensure that your instruments can be safely utilized. |
| 1. |
Visually check the adjustment level knob(s)
| a. |
If the knob(s) appears to be damaged or cracked, please contact your nearest HIOKI distributor to have your instrument repaired immediately. |
 |
| b. |
Check to see that the sealing compound has not bee removed from the knob. As shown below, if the sealing compound is attached, you can safely use the instrument. |

|
| c. |
If the sealing compound appears to have separated, you should be able to see the fixing screw. In this case, please arrange to have the instrument repaired. |
|
|
| 2. |
In new units, knob covers will be used to prevent the sealing compound from detaching, as shown below.
