Electro-Chemical Devices (ECD) CA6 Hardness Analyzer - Manual (Page 26)

Calibration
Calibration sets the time in seconds, to calculate and record a new calibration factor after a calibration
extra cycle, Auto Calibration. Typically 1 – 2 seconds
Validation
Validation sets the time, in seconds, to calculate and display % Validation of a Known Standard in the
display screen using the current calibration factor as a calibration check. A 5 ppm sample reading 4.8
ppm, displays 96% after the validation extra cycle. Typically 1 – 2 seconds
Blank
The Blank function sets the time, in seconds, to enter a new blank calibration, calculating and recording
the new blank value in the calibration screen after a Blank extra cycle. Typically 1 – 2 seconds
Save Dtlog
Allows the measurement's reading to be saved in the internal Data logger, Typically 1 – 2 seconds, the
data log register is only written to after the internal 24 hour clock resets to 00:00:00
Relay #1
The Rele #1 setting allows a time, in seconds, to be assigned to the activation of relay 1. The relay
configuration is set in the Service Menu.
Relay #2
The Rele #2 setting allows a time, in seconds, to be assigned to the activation of relay 2. The relay
configuration is set in the Service Menu.
2.4 Components
The CA-6 Analyzer has three distinct sections:
1. The Liquids Section which includes all of the liquid
handling equipment. This is located in the Lower
Compartment, (pictured right, with Dilution Module).
2. The Electrical Section including power supply,
microprocessor controller, I/O and touch screen
interface are located in the Upper Compartment.
3. Reagents Section, the CA-6 can use up to 4 reagents,
these containers are typically stored below or beside
the analyzer.
2.4.1 Fast-loop reservoir
The external Fast-Loop Reservoir is a sample collection and
conditioning chamber for a sample coming from a pressurized
line or from the optional filtration unit. The overflow design
removes variations in sample line pressure as well as eliminating
any air bubbles from the sample line or bubbles generated by
the cleaning cycle of the optional filtration unit. Inside the fast-
