Safety Tip: Stay Safe with Bluetooth Technology

When troubleshooting or starting up a control system, it’s often necessary to take electrical readings using portable test instruments. For years, the most common way of doing this was to use the proper PPE (personal protection equipment) as outlined in NFPA 70E, and take live measurements. This method inherently puts people at an increased risk [...]
