10 Appendix B: Single turbidity measurement and built-in temperature
measurement with optical wiping
10.1 Script objectives
This script can be loaded onto all NEP-695 logging probes using the CR-300 PW200 application. The
script turns on the sensor. After the warm up time elapses, it performs an optical wiping followed by a
single turbidity measurement, a temperature measurement and stores data at each scan (every 5
minutes). Then the script calls two data tables and stores the data within the datalogger:
•
The script records the wiping status (if jammed or not) of the probe (Wipe_stats) and the turbidity
(Turbidity) in NTU and the liquid temperature (Liquid_Temp) within a data table (Table1) at each scan
(every five minutes).
•
The script records the minimum default CR300 Battery Voltage (BattV) and the processor temperature
measurement (PTemp_C) within another data table (Table 2) once a day.
The script uses the SDI-
12 command “M1!” to trigger a wipe, the command “M!” to perform a turbidity
measurement and “D1!” to perform a temperature measurement.
10.2 Wiring & NEP-5000 configuration
Please refer to
section 6.1
“Connect NEP-695 to a single NEP-5000” to properly setup and connect the
logging probe to the NEP-5000 sensor.
Connect the NEP-5000 probe to your Windows computer using the
“Blue Box”. Configure the NEP-5000
ranges using the NEP-5000 software. Apply SDI-12 settings.
To commit above settings to permanent memory please press set followed by save calibration
Please refer to the NEP-5000 manual for more information.
