Calibration 85
10.9 Calibrating Temperature
Most liquid analytical measurements require temperature compensation (except ORP). The
56 performs temperature compensation automatically by applying internal temperature
correction algorithms. Temperature correction can also be turned off. If temperature
correction is off, the 56 uses the manual temperature entered by the user in all temperature
correction calculations.
To calibrate temperature, access the Calibration screen by pressing ENTER/MENU from the
main screen, select S1 or S2 Temperature and press ENTER/MENU. Press INFO at any time to
learn more about this procedure. A
yellow screen will appear with detailed
instructions and information.
The following calibration routine is
covered:
1. Temperature with manual
temperature entry
2. To Calibrate Temperature, follow the
step-by-step procedures
displayed on-screen.
10.10 Turbidity
This section describes how to calibrate the turbidity sensor against a user-prepared standard
as a 2-point calibration with deionized water, against a 20 NTU user-prepared standard as a
single point calibration, and against a grab sample using a reference turbidimeter.
To calibrate the turbidity sensor, access the Calibration screen by pressing ENTER/MENU from
the main screen, select S1 or S2 Measurement and press ENTER/MENU. Press INFO at any time
to learn more about this procedure. A yellow screen will appear with detailed instructions and
information.
The following calibration routine is
covered:
1. Slope Calibration Slope cal with pure
water and a standard of known tur-
bidity
2. Standardize Calibration
Standardizing the sensor to a known
turbidity
3. Grab Calibration Standardizing the
sensor to a known turbidity based on a
reference turbidimeter
