Rosemount Handheld DeviceThe open communication protocol for addressable remote sensor high-speed channels is a communication protocol used between on-site intelligent instruments and control room equipment. It can be used to complete almost all on-site instrument maintenance and debugging work, including fault diagnosis, daily maintenance, driving debugging, calibration, etc.
Function:
1. Low voltage alarm: When the battery voltage is too low, the "battery" indicator appears. We don't need to say much about this feature, it's just a battery level prompt, which is also common on mobile phones and easy to understand.
2. Automatic power off: Just like using a mobile phone, if you don't move for a few minutes, you will be in a sleep state. Of course, the Rosemount handheld device is not in a sleep state, but directly automatically shuts off the power. The duration for the machine to automatically turn off the power is 5 minutes. The duration of a typical calculator is one minute. Here are examples only to better illustrate these nostalgic '* functions'.
3. The data set by the transmitter connected to the handheld device can be transmitted in batches to the machine's memory. Downward transmission can write data to the instrument, but cannot be written to different models of instruments (to protect the transmitter from confusion)
4. Print output: Supports multiple printing methods, such as listing all parameters, etc. This feature was considered a very advanced technological process at that time.
5. Language selection: The Rosemount handheld controller supports multiple languages, making it easy to use.
6. LCD contrast: This is easy to understand, which is commonly referred to as the contrast between the brightness setting of the screen and the text background.
