4-wire measurement on up to 20 channels with MUX extension.

HIOKI RM3546 Resistance Meter

The HIOKI RM3546 is a high-precision DC resistance meter optimized for weld resistance inspection on battery cells and modules. The RM3546 offers Active Circuit Protection up to DC 60 V, a high path resistance tolerance, 13 ranges from 1 mΩ to 1000 MΩ, and max. 1 A test current. With the multiplexer option Z3003 measurement systems with up to 20 channels (4-wire mode) are possible. For remote control the device has LAN/Ethernet, RS232C, or USB.

Resistance ranges 1 mΩ...1000 MΩ (13 ranges).
Active Circuit Protection DC 60 V.
Path resistance tolerance up to 9 Ω (PR mode, 500 mA).
Maximum test current 1 ADC.
Ultra-high precision measurement with 1 nΩ resolution.
Multiplexer option with Z3003 for up to 20 measurement channels (4-wire mode).
Applications:
- Automated battery cell tab weld resistance inspection.
- Busbar weld resistance inspection in battery modules.
- Manual resistance measurement of battery module connections.
- Automated multi-point resistance measurement using Z3003 multiplexer option.
