While watching the display on the electronic counter to see if it changes, slowly tip the bucket until it drops to the opposite side. If the display does not change, you may be tipping the bucket too quickly. Try again, more slowly this time. If the electronic counter display increases by 0.01” (or 0.2 mm if you have the metric rain collector) each time you tip the bucket, your electronic counter is working properly and you may continue the installation. 4. Clear the rainfall amount by pressing the button on the front of the electronic counter. U SING THE E LECTRONIC C OUNTER After installing the rain collector, connect the rain collector and electronic counter by plugging the rain collector cable into the coupler at the end of the electronic counter’s cable. Once connected, the electronic counter continually tracks and displays rainfall in either 0.01” or 0.2 mm increments (depending on the model you own). You may display the electronic counter on a wall, shelf, table, or other similar surface. To Display the Electronic Counter on a Wall Slide the wall mounting bracket over the end of the electronic counter. The slots on the side of the electronic counter act as a guide. Remove the backing from the adhesive pad on the back of the mounting bracket and stick the mounting bracket (and electronic counter) to the wall in the desired location. To Display the Electronic Counter on a Shelf or Table Pop the brace free from the battery cover. You may wish to use a coin, small screwdriver, or a fingernail in the slot at the bottom of the unit to get the brace free. Use the brace to prop up the electronic counter on any flat surface (desk, table, shelf, etc.). DISPLAYING ON A SHELF OR TABLE Using the Electronic Counter Page 3 To Clear the Electronic Counter Press the button on the front of the electronic counter. This resets the rainfall amount to 0. T ECHNICAL S UPPORT Before calling Technical Support (1-510-732-7814), carefully check all cable connections from the rain collector to the electronic counter. Cable connections account for a large portion of the potential problems. Connections should be firmly seated in the jacks and plugged in straight. If you think a connection may be faulty, try jiggling the cable while looking at the display. If a reading appears intermittently on the display as you jiggle the cable, the connection is faulty.
