4. For devices with intrinsically safe protection type, use an isolating power supply that
corresponds to the requirements of the relevant type of protection.
5. Switch on the power supply.
Switching on the supply voltage (Page 128)
6. Wait for 2 seconds.
After this startup time, the device is operational.
7. Wait 5 minutes to get exact measured values.
8. Lock the device.
