8. Operation

8.1 Sensor schematic

Campbell Scientific installs a 100 Ω resistor, connected in series, at the switch to prevent arcing by
limiting current (

FIGURE 8-1

(p. 12)).

FIGURE 8-1. TE525-series rain gage schematic

8.2 Measurement

Campbell Scientific data loggers measure TE525 rain gages by counting switch closures and
converting the total to rainfall. The

PulseCount()

instruction employs dedicated pulse count

accumulators, which continuously monitor the input signal, even when the data logger is
between program scans. To create a pulse, an internal 100 kΩ pull-up resistor pulls the pulse
input to 5 VDC when the switch is open, and a switch closure to ground pulls the input to 0 VDC.

9. Troubleshooting and
maintenance

NOTE:
All factory repairs and recalibrations require a returned material authorization (RMA) and
completion of the “Declaration of Hazardous Material and Decontamination” form. Refer to
the

Assistance

page at the back of this manual for more information.
