Description Of Controls; 3.1 Keyboard Functions - Emerson Rosemount 1054B Instruction Manual

MODEL 1054B pH/ORP

3.1 KEYBOARD FUNCTIONS.

All functions of the 1054B are accessed through key-
board entry routines. The analyzer uses no switches or
potentiometers.
The four keys across the top row and the CAL (pH only)
and ENTER keys are dual function. One press of the
key will display the value of the function shown on the
lower portion of the key. A quick double press of the key
will display the value of the function shown on the upper
portion of the key. Each of these keys have read func-
tions that can be accessed without security code entry.
Each key also has a calibration or set function when
used with the SELECT key. This function requires entry
of the security code when the security feature is active.
(Refer to Section 6.0 for keyboard security.)
NOTE
When no key is pressed for a period of 60 sec-
onds the analyzer will default to reading pH.
CAUTION
The HOLD function and the CAL function
are not read functions. Refer to Section 5.3.
A. Standardize pH/ORP. Standardi-
zation of the pH/ORP sensor is achieved
OUTPUT
by pressing the PV key once, followed
immediately by pressing the SELECT
PV
key. Std displays to acknowledge the
standardize function, followed by the
Numeric Display for user input. Entering
the known pH/ORP of the measured
solution will cause the analyzer to
restandardize the sensor. The pH glass
slope value will not be changed. Refer to
Section 5.4.
B. Standardize Temperature. Stand-
HOLD
ardization of the temperature is achieved
by pressing the TEMP key once, followed
TEMP
immediately by pressing the SELECT
key. AdJ displays to acknowledge the
standardization function, followed by the
Numeric Display for user input. Entering
the known temperature of the measured
solution will cause the analyzer to
restandardize the temperature reading.
Refer to Section 5.2.

DESCRIPTION OF CONTROLS

C. Alarm 1 and Alarm 2 Setpoint. The
ZERO
alarm setpoint may be adjusted by
pressing the ALARM 1 or ALARM 2 key
ALARM 1
once, followed by pressing the SELECT
key. AdJ displays, followed by the
Numeric Display for user input. Refer to
Section 4.10.
D. Current Output – Zero Setpoint. The
ZERO zero point (0 or 4 mA) of the pH output
range is adjusted by pressing the ZERO
ALARM 1 key twice, followed by pressing the
SELECT key. AdJ displays, followed by the
Numeric Display for user input. Refer to
Section 4.11.
E. Current Output – F.S. Setpoint. The
full scale point (20 mA) of the pH output
F.S.
range is adjusted by pressing the F.S. key
twice, followed by pressing the SELECT
ALARM 1
key. AdJ displays, followed by the
Numeric Display for user input. Refer to
Section 4.11.
F. Two Buffer Calibration (pH). A two
buffer calibration is initiated by pressing
the CAL key once. Refer to Section 5.3.
CAL
Calibration (ORP). A calibration is
initiated by pressing the CAL key once.
Refer to Section 5.3.
G. pH Glass Slope. The millivolt output
per pH unit is adjusted by pressing the
CAL key twice, followed by pressing the
CAL SELECT key once. AdJ displays, followed
by the Numeric Display for user input.
Refer to Section 5.5.
H. Simulate Current Output. The pH
output can be simulated by pressing
OUTPUT
the PV key twice, followed by pressing
the SELECT key. The Numeric Display
PV
appears for user input. Refer to
Section 4.12.
