Ametek 241CE II

4-14 | Model 241CE II Hydrocarbon Dewpoint Analyzer
Sub-Menu Item Description
Tz This system status parameter (T) indicates the Run-Time (Days Hours:Minutes – 000 00:00) at the
beginning of the Cooling Stage for each of the last nine measuring cycles (where ‘z’ = 1–9: ‘1’ = most
recent entry and ‘9’ = oldest entry).
^WDz This history bu󰀨er displays the Water Dewpoint temperature (°C or °F) for the last nine measuring
cycles (where ‘z’ = 1–9: ‘1’ = most recent entry and ‘9’ = oldest entry).
Note: This signal will be displayed only if an external water signal is provided and if
the H2O DP:EXT option is enabled from the MonitorCFG menu. If the H2O
DP:INT option is enabled, the WDP readings are derived from the internal
water mirror surface – not recommended.
^HCDz This history bu󰀨er displays the Hydrocarbon Dewpoint temperature (°C or °F) for the last nine mea-
suring cycles (where ‘z’ = 1–9: ‘1’ = most recent entry and ‘9’ = oldest entry).
^WCz This history bu󰀨er displays the external Water Content (optional, if used) in mg/m
3
, lb/MMcf, PPMV,
or PPMW values for the last nine measuring cycles (where ‘z’ = 1–9: ‘1’ = most recent entry and ‘9’ =
oldest entry).
Note: This signal will be displayed only if an external water signal is provided and if
the H2O CT:EXT option is enabled from the MonitorCFG menu. If the H2O
DP:INT (with water content) option is enabled, these readings are derived from
the internal water mirror surface – not recommended.
^WMirz n This history bu󰀨er displays the phototransistor signal from the Water-side of the mirror at the start of
the Run cycle, for the last nine measuring cycles (where ‘z’ = 1–9: ‘1’ = most recent entry and ‘9’ =
oldest entry, and where ‘n’ = the displayed phototransistor signal value).
^HCMirz n This history bu󰀨er displays the phototransistor signal from the Hydrocarbon-side of the mirror at the
start of the Run cycle, for the last nine measuring cycles (where ‘z’ = 1–9: ‘1’ = most recent entry and
‘9’ = oldest entry, and where ‘n’ = the displayed phototransistor signal value).
^SCz n This history bu󰀨er displays the basic Status Code alarms for the last nine measuring cycles (where
‘z’ = 1–9: ‘1’ = most recent entry and ‘9’ = oldest entry, and where ‘n’ = the total sum of all primary
SCode alarms triggered during the last measuring cycle).
^XSCz n This history bu󰀨er displays the basic Extended Status Code alarms for the last nine measuring cycles
(where ‘z’ = 1–9: ‘1’ = most recent entry and ‘9’ = oldest entry, and where ‘n’ = the total sum of all
primary XSCode alarms triggered during the last measuring cycle).
EEP WR n This system status parameter displays the number of writes (‘n’ = total number of writes) to the ana-
lyzer’s EEPROM (changes to the system conguration settings).
000000000-1 This system status parameter displays the Serial Number of the analyzer.
M241 Vx-xx This system status parameter displays the current Firmware Version running the Model 241CE II
Analyzer.
