Meter Setup Menus
Mode and Settings Menu for pH/ISE Channel
Use the Mode and Settings menu to customize the measurement, calibration and alarm settings
for the pH/ISE channel of Orion Star A214 pH/ISE meters. Default meter settings are bold.
Parameter
Settings
Details
Measure Mode
•
pH
•
mV
•
RmV
•
ORP
•
ISE
Set the displayed measurement mode, the selected
mode determines which additional settings are shown
and the type of calibration the meter will perform
Read Type
•
Auto
•
Continuous
•
Timed 00:00:03
Set the read type to determine how the meter takes a
measurement and when the measurement is sent to
the data log and/or external device
Resolution
(pH only)
1 Decimal Place
2 Decimal Places
3 Decimal Places
0.1
0.01
0.001
Set the resolution of the pH measurement value
Buffer Group
(pH only)
•
USA
•
DIN
Set the buffer group for automatic buffer recognition
during pH calibrations
USA: pH 1.68, 4.01, 7.00, 10.01 and 12.46 buffers
DIN: pH 1.68, 4.01, 6.86 and 9.18 buffers
Resolution
(ISE only)
1 significant digit
2 significant digits
3 significant digits
Set the resolution of the ion concentration (ISE)
measurement value
Measure Unit
(ISE only)
•
ppm
•
M
•
mg/L
•
Percentage (%)
•
ppb
•
None
Set the units displayed with the ion concentration
(ISE) measurement value
Blank Correct
(ISE only)
•
Yes
•
No
Set the automatic blank correction function off or on
for ISE measurements, when the function is on – an
algorithm is used to compensate for the non-linear
response of the electrode in low level standards and
samples for improved measurement stability
Stability
•
Smart Stability
•
Fast
•
Medium
•
Slow
Set when a measurement is recognized as stable,
Smart Stability compensates for measurement
conditions and optimizes the meter response time
Averaging
•
Off
•
Automatic Smart
Set averaging for faster measurement stability,
Automatic Smart compensates for measurement
conditions and optimizes the meter response time
Limit Alarm
•
Limit Alarm
Off On
•
Alarm Settings
High High/Low Low
•
High Limit
•
Low Limit
Set the limit alarm off or on, when alarm is on – set the
alarm setting as high, high/low or low and then enter
the appropriate measurement limit values
The limit alarm is triggered when the measurement
goes above the high limit or below the low limit
Cal Due Alarm
(pH, RmV, ORP
and ISE only)
•
Cal Due Alarm
On Off
•
Cal Due Limit
12 Hrs
Set the calibration due alarm off or on, when the cal
due alarm is on – enter the calibration time interval in
hours (1 to 9998 hours)
The cal due alarm is triggered after the entered time
has elapsed without a calibration being performed
Low Lv Stability
•
Off
•
On
Set the low level stability function off or on for ISE
calibrations, when the function is on – the minimum
stabilization time is increased (~3-5 minutes) to
improve accuracy in low level calibration standards
