Configuration
The METERdat™ circuit boards are configured through the RS-232 port using the OnBoard© software. Measurement parameters such as the UWI, ID, pen ranges, atmospheric pressure, and sample rate are initialized on the circuit board and recorded at the beginning of each memory module and file.

Calibration
Calibration values are set by zeroing the pens and following the entry sequence described in the operating instructions. The calibration should be updated if the circuit board is removed and reinstalled for recorder maintenance purposes.

Sleep Mode
The circuit board will power down after 30 minutes of inactivity. No LED's will be lit. Press the front log button to wake it up. The LED's will display the pen test and the unit will enter Safe Mode. The red LED will then be on.
