4. Calibration Instructions

A two-point calibration is adequate because the load cell is linear to within 2.5
grams (0.003” rain equivalent). This calibration procedure assumes the user
has a properly mounted, level, and fully functional RDP500 weighing style rain
gauge.

1. Begin by removing the top hood from the rain gauge and emptying,

drying, and cleaning out the rain gauge catch basin. Make sure proper
HAZMAT protocols are followed to dispose of the liquid in catch basins
containing oil or antifreeze.

2. Open the exterior rain gauge access door and the internal enclosure door to

gain access to the datalogger.

3. Insert the male end of the SC12 cable (provided) into the CS I/O port on

the wiring panel of the CR1000 datalogger and connect either female end
to the CR1000KD keyboard display module.

A standard serial cable may be substituted for the SC12 cable.

NOTE

Once powered, the CR1000KD will light up and display the default
Campbell Scientific screen.

If the CR1000KD times out and the screen goes blank, simply press any
key to re-activate the keyboard display. The Esc key is used to navigate
backwards through the custom menu.
