Frequently Asked Questions - CB-832 Megger
What is the Megger CB-832 used for?
The Megger CB-832 is a cable fault locator used to identify faults such as opens, shorts, and splices in metallic cables using Time Domain Reflectometry (TDR) technology.
How do I change the batteries in the CB-832?
To replace batteries, turn off the device, remove the battery cover on the back, insert 6 x 1.5 V AA batteries (or rechargeable) observing polarity, then replace the cover.
What types of cables can I test with the CB-832?
The CB-832 works on most metallic cables including twisted pair, coaxial, and power cables, with a range up to 2000 m depending on cable impedance and attenuation.
How do I interpret the TDR trace on the display?
The trace shows reflected pulses. A positive reflection indicates an open or high impedance, a negative reflection indicates a short or low impedance. The distance is read from the cursor position.
Can the CB-832 be used on live circuits?
No, always disconnect and de-energize the cable before testing. The device is designed for low-voltage testing only and is not rated for live work.
What is the maximum distance the CB-832 can measure?
The maximum range is 2000 m (about 6560 ft) for typical cables, but actual range may vary based on cable type, gauge, and condition.
How do I calibrate the CB-832?
The device self-calibrates on startup. For accurate measurements, ensure the cable type and propagation velocity (Vp) are correctly set in the menu.
What accessories come with the CB-832?
Standard accessories include: test leads with alligator clips, a carrying case, a USB cable, and a quick start guide. The full manual is available online.
How do I transfer data from the CB-832 to a computer?
Connect the device to a PC via the USB port. Use Megger's software (downloadable from their website) to download traces and generate reports.
Is the CB-832 waterproof?
No, but it has an IP54 rating, meaning it is protected against dust and splashes from any direction. Do not submerge in water.
