Information about current and frequency detection, current exposure, and safety around magnets and moving equipment.
Important use information
- Voltage is not designed to replace any step in existing safety procedures; it helps detect human error in everyday work processes
- Voltage should be used by suitably trained personnel (qualified or unqualified)
- Voltage is a proximity sensor; never contact energized equipment
- If Voltage is used without fully understanding the interface and limitations, serious injury can occur
- Static may produce false alarms
- Voltage's detection will be impacted by situations that result in energized equipment producing a weaker field, such as 3 phase equipment, grounded equipment, equipment that is close to the ground, and when gear is wet
- Use only on the wrist; do not attach the wristband to other equipment or to a hot stick
Current and frequency detection
The Proxxi Voltage Wristband uses an internal electrometer to wirelessly sense electrical potential (an energized voltage differential).
The wristband should only be used in AC environments.
The firmware is filtering the electrometer readings to specifically look for alternating current (AC) of a particular frequency to prevent false positive readings.
The Proxxi Voltage Wristband is not recommended for DC environments as it will not alert to DC voltage.
The wristband is configured to alert for 50Hz or 60Hz.
Like a serial number, the 60Hz vs 50Hz configuration is written in programming and can never be changed again.
On the underside of the wristband, it will denote which frequency the wristband is programmed for. Ensure the wristband you are using is the correct frequency for your environment.
Electrical current exposure
There are no exposed electrodes, terminals, or connectors. All currents stay safely within the wristband.
Medical safety with magnets
There are no magnets in the Voltage Wristband other than those contained within the vibration motor, which are very small.
Due to the small size, metal shell of the motor, and distance of the motor from the wrist when worn, the magnetic field at the wrist is virtually non-existent. If you are able to wear a typical fitness tracking style device, smartwatch, or hold a phone, this will be no different.
Safety around moving equipment
The Proxxi Voltage Wristband is designed to be quick-release to help keep workers safe.
If you need to secure your Wristband, you can use the keeper, which is a plastic loop that helps hold the wristband straps together, like on a watch.
