DESCRIPTION OF CONTROLS

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

by pressing the 

PV

key once, followed

immediately by pressing the 

SELECT

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-

ardization of the temperature is achieved

by pressing the 

TEMP

key once, followed

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.

C. Alarm 1 and Alarm 2 Setpoint. 

The

alarm setpoint may be adjusted by

pressing the 

ALARM 1

or 

ALARM 2

key

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 point (0 or 4 mA) of the pH output

range is adjusted by pressing the 

ZERO

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

range is adjusted by pressing the 

F.S.

key

twice, followed by pressing the 

SELECT

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.

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

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

the 

PV

key twice, followed by pressing

the 

SELECT

key. The Numeric Display

appears for user input. Refer to

Section 4.12.
