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 Relay #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 Relay #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-loop reservoir the sample is at
atmospheric pressure and this allows the sample pump to provide a
consistent sample delivery to the colorimetric cell. In addition, the
fast-loop reservoir provides an extra quantity of sample in case of an
interruption in the sample flow.
The stainless steel drain tubing keeps a constant sample level inside
the container. The sample flow should be adjusted for a continuous
sample overflow through the stainless steel drain tube thereby
providing ample circulation to avoid suspended solids accumulation
in the reservoir. A small hole at the top of the stainless steel drain
tubing allows the fast-loop reservoir to be easily emptied for
cleaning purposes.
The Fast-Loop reservoir uses a level sensor to verify sample volume.
The loss of sample triggers the level switch which places the
analyzer in stand-by mode at the end of the current measurement
cycle. When the sample flow returns and refills the reservoir, the
analyzer will automatically start a new cycle.
