Notice of Component and Specification Changes to Voltage Module VIM-3010
Due to the discontinuation of the CPU used in the Voltage Module, certain components have been replaced, resulting in a change to the input impedance specification.
Affected Product
Voltage Module VIM-3010 (for RTR505B and TR-55i-V)
Specification Change
The input impedance, which previously differed depending on the measurement range, has been changed to about 1.1 MΩ for both ranges.
| Measurement Range | Previous Specification | New Specification |
|---|---|---|
| mV Range | About 3 MΩ | About 1.1 MΩ |
| V Range | About 1 MΩ | About 1.1 MΩ |
Note: This change will not affect normal measurement results. However, when using the mV Range with a special sensor that has an extremely high output impedance, measurement errors may increase.
How to Identify Products with the New Specification
Products manufactured beginning in July 2026 will have the new specification. Shipment of products with the new specification will depend on inventory availability. The product version can be identified by the serial number (No.) printed on the Voltage Module.
| Product Version | Serial Number |
|---|---|
| Previous Version | No. 08130000 or earlier |
| New Version | No. 08130001 or later |
