If a sensor is Enabled that isn’t connected to the
instrument, the display will show an unstable false
reading, ?????, or ----- next to the units.
DISPLAY - oRP
Press Sensor , highlight Display and press
enter.
Highlight ISE (ORP) and press enter. You will
not be able to Display the sensor unless it is
Enabled in the Sensor Setup menu.
Press enter to enable (
Q ) or disable ( P ) ORP
mV.
AUto StABLE - oRP
Press Sensor , highlight Auto Stable and
press enter. Highlight ISE (ORP) and press
enter.
Auto Stable indicates when a reading is stable.
Highlight Enabled and/or Audio Enabled
(instrument will beep when the stability is
achieved) and press enter enable (
Q ) or disable
( P ). When Auto Stable is enabled, AS will blink
next to the parameter until it is stable. once the
parameter is stable, AS will stop blinking.
the Auto Stable Sensitivity can be decreased or
increased. Highlight Sensitivity and use the left and right arrow keys to slide
the bar. the more sensitive you make it (larger black bar) the harder it is to
achieve stability in a changing environment.
the Auto Stable system works by examining the previous 5 readings, computing
the percent change in the data and comparing that change against a % threshold
value. the % threshold value is determined by the Sensitivity bar setting. the
following chart can be used as a guide when setting the Sensitivity bar.
The actual readings displayed during the calibration will
NOT reflect the updated calibration information. These
values will not change until Cal is pressed to finalize
the calibration and to update the instrument.

oRP sensors can be used on 60510-X, 6051020-X, 6051030-X, 6051010-X, and
Quatro cables.
If using a 605103 pH/oRP combination sensor on a 6051020 or 6051030 cable
you can report both pH and oRP by configuring ISE1 as pH and ISE2 as oRP
in the Sensor Setup menu.
the 605103 pH/oRP combination sensor is not recommended for use on a
6051010 or Quatro cable. If used on one of these cable, only pH will be reported
and oRP will not be measured.
SEtUP - oRP
Press Sensor , highlight Setup, press enter.
Highlight ISE1 if using a 605102 (oRP sensor)
on a 60510, 6051020, or 6051030 cable. Highlight
ISE2 is using a 605103 (pH/oRP sensor) on a
60510, 6051020, or 6051030 cable. If using a
6051010 or Quatro cable, highlight ISE1 if the
oRP sensor is installed in port 1 or highlight
ISE2 if the oRP sensor is installed in port 2 (a
sensor must be installed in port 1 for port 2 to
operate). Press enter.
Enabled allows you to enable or disable the ISE
function and select which ISE sensor is installed
on the cable. Highlight Enabled and press enter
to enable (
Q ) or disable ( P ) the ISE you selected
previously (either ISE1 or ISE2).
After enabling the ISE function, ensure oRP is
selected as the ISE sensor as shown in screen
shot to the left. If necessary, highlight oRP and
press enter to set the selected ISE to oRP.
