11.1.1.3 Register Functions
11.1.1.3.1 Test Mode
Factory set value: 0
This is the "test mode", each bit represents an option corresponding to a tick box on the CMS settings screen (see
our RMF-View software and in the CMS manual).
Each bit of the register encodes one tick box.
The factory set mode is 0 for all bits, so all the tick boxes are turned off. You may want to turn on bit 8 (disable
low flow alarm when clean) if you have a very clean system.
Here are the bit definitions:
Bit Function Comment
0 CYCLE_COTINUOUS Continuous Testing
1 START_TEST_AUTOMATICALLY Start Testing Automatically
2 CONTINUOUS_STOP_WHEN_CLEAN Stop Testing When Clean
3 CONTINUOUS_LOG_EVERY_TEST Continuous Mode: Log Every Test
4 CONTINUOUS_CONFIRM_TARGET Repeat final test to confirm target level achieved
5 RESERVED
6 RESERVED
7 SIMULATE Produces simulated test results
8 LOW_FLOW_CLEAN_DISABLED Prevents spurious low flow alarms on clean systems
Table 11B Test Mode Register Bit Definitions
There is some general information about what these options do in section 6.3.3.
11.1.1.3.2 Command Register
This is register 21. It is special in that writing a number to this register does not store the number, but instead
commands the CMS
to perform a function according to the number written. The main command is ``START’’, but
the others are documented here for completeness and avoidance.
