Digital ohmmeter CTI46

bench-toprack-mount4-wire

Product overview
The CTI46 is a multi-channel safety pyrotechnic ohmmeter (1 channel standard, up to 4 channels optional) for carrying out measurements on pyrotechnic devices. Developed for use in industrial environments, it is suitable for integrated controls on production lines as well as for laboratory testing. Designed for measurements on pyrotechnic elements where operator safety is critical, it combines measurement versatility with high speed. The instrument can be fully controlled via RS232 or Ethernet.

Safety features

• Measuring current much lower than non-fire current
• Connection to the test line only during the measurement period
• Failsafe limiting to a maximum safety current in case of equipment failure (electronic fault, internal short circuit, etc.)
• Discharge path for residual electrostatic charges at rest
• Continuous self-monitoring of internal functions
• External safety loop authorising powering of the measurement circuits

Instrument functions

• Ohmmeter: up to 4 main measurement channels using the 4-wire technique to eliminate cable resistance; inter-channel measurements for complex configurations
• PT100 function: temperature measurement
• Macro: creation and execution of grouped measurements as macro commands
• Display: configurable LCD screen
• Communication: configure or control via Telnet, TCP (Ethernet) or RS232
• Major characteristics: 4/8 channels; Ohmmeter ranges: 1 Ω / 10 Ω / 100 Ω / 1 kΩ / 10 kΩ; 19" 2U P260 benchtop or rack cabinet
