4.22 Measure Menu [MEASURE]
The default menu for the system is the display-only menu MEASURE. This menu
is a display-only measurement menu, and has no changeable list items. When
left alone, the instrument will automatically return to this menu after
approximately 30 minutes. While in the default menu, the UP arrow allows the
user to scroll through the secondary variables on the lower line of the display. A
brief description of the fields in the basic transmitter version is as follows:
TRANSMITTER MEAS SCREENS:
25.7°C
Temperature display. Can be displayed in °C or °F,
depending on user selection. A small “m” on the left side of
the screen indicates the transmitter has automatically
jumped to a manual 25°C setting due to a failure with the
temperature signal input.
TDS = 200 ppm
Total Dissolved Solids (TDS). Displays TDS of process.
20.00 mA
Transmitter output current.
Slope = 100%
Sensor output response vs. ideal calibration. This value
updates after each calibration. As the sensor ages, the slope
reading will decay indicating sensor aging. Useful for
resolving sensor problems.
Q45C2 v2.04
Transmitter software version number.
Note: A display test (all segments ON) can be actuated by pressing and
holding the ENTER key while viewing the model/version number on
the lower line of the display.
For the relay-based analyzer version, or the portable battery powered version of
the transmitter, the screens are basically the same, with additions to show two
analog outputs instead of one (#1 and #2.)
The MEASURE screens are intended to be used as a very quick means of
looking up critical values during operation or troubleshooting.
