Product Overview
The Honeywell 1146B AC/DC Current Probe offers precise current measurement up to 100 A DC or peak AC with a frequency range of DC to 100 kHz. This probe replaces the discontinued 1146A while maintaining the same form, fit, and functionality, making it a direct upgrade for existing systems. Using hall-effect sensor technology, the Honeywell 1146B delivers reliable readings without breaking the circuit.

Applications
The Honeywell 1146B excels in capturing transient current signals in motor controllers, switching power supplies, inverters, and current amplifiers driving inductive loads. Engineers use this probe for troubleshooting power electronics and verifying waveforms in R&D labs. Its wide bandwidth and high current capability make it suitable for both AC and DC measurements in industrial automation.
Installation and Setup
Connect the Honeywell 1146B to any oscilloscope with 0.2 to 0.5 V/div sensitivity and a 1 MΩ BNC input. Insert a 9 V alkaline battery before use. Clamp the probe around the conductor under test, ensuring proper orientation for accurate readings. The compact design allows easy placement in crowded panels.
Maintenance and Reliability
Regularly check the battery level; low battery can affect accuracy. Store the probe in a dry, clean environment when not in use. The rugged construction withstands typical industrial conditions. Replace the battery annually or as needed. No routine calibration is required, but periodic verification against a known source is recommended.
Compatibility
The Honeywell 1146B works with any Keysight oscilloscope that meets the input sensitivity requirement. It is also compatible with other brands of oscilloscopes and data acquisition systems that have BNC inputs and 1 MΩ impedance. This flexibility makes it a versatile tool for test benches and field service.
Buying Guide
When purchasing the Honeywell 1146B, verify that it matches your current measurement needs (up to 100 A). Consider the battery type (9 V alkaline) and ensure you have a compatible oscilloscope.
