Data logging
The sc controller provides one data log and one event log for each instrument. The data log stores
the measurement data at selected intervals. The event log stores different types of events that occur
on the devices (i.e., configuration changes, alarms and warning conditions).
The data log and the event log can be saved in CSV format. Refer to the sc controller user manual
for instructions.
Calibration
Calibration is done in the body of the instrument or using the optional calibration kit.
Calibration is done using 1 L of 800 ± 50 mNTU StablCal Stabilized Formazin Certified Standard. Do
not use other types or values of standards. Do not use user-prepared formazin.
The performance specifications given in this manual are based on and guaranteed only when
calibration is done with StablCal Stabilized Formazin Certified Standard for this instrument. The
manufacturer cannot guarantee the performance of the instrument if calibrated with co-polymer
styrenedivinylbenzene beads or other suspensions.
Prepare the StablCal
• Before opening a StablCal Standard bottle, clean the exterior surface of the bottle with clean water
to remove dust or other debris.

Description
Enable or disable bubble reject—Yes (default) or No
Bubble reject is an averaging algorithm that compensates for higher readings caused
by entrained air coming out of the solution in the sample chamber.
Select no signal averaging or the amount of time for signal averaging—no averaging, 6,
30, 60 or 90 (default) seconds.
Select the measurement units to show on the display—mNTU (default), mFTU, NTU,
FTU, mg/L or Degree.
Change the name to show on the display for the instrument. The instrument name can
be a maximum of 12-digits in any combination of symbols and alpha or numeric
characters.
Note: The serial number of the instrument is the default name.
10 or 15 (default) minutes.
Sets an offset of the value of the standard used for calibration (-50 to +50 mNTU,
default=0).
The offset value is subtracted from the calibration standard value shown on the sc
controller.
The offset can be entered after a calibration is complete and is based on independent
turbidity measurement of the calibration standard.
Note: The offset will not result in a calibration standard value of less than zero on the
sc controller.
