Within the Auto Stable menu, you can also
choose to Hold All Readings for as many
parameters as you set for Auto Stable. For
instance, if oRP and pH have Auto Stable
enabled and Hold All Readings is enabled,
then the display will hold the readings once
oRP and pH have both reached their Auto
Stable settings. You must press the Esc key
to "release" the held display in order to take
subsequent readings. Hold All Readings must
be reactivated after each use!

calibration. When enabled, these IDs are stored
with each calibration record in the GLP file.
After selecting your User ID and/or Probe
ID if appropriate, highlight ISE (ORP) and
press enter. the message line will show the
instrument is "Ready for point".
Place the sensor in a solution of known oRP
and wait for the readings to stabilize.

If using the YSI Zobell calibration solution,
the Pro Plus will automatically determine the
calibration value. However, the calibration value
should be verified against the chart on the side
of the Zobell bottle. Next, once the temperature
and oRP readings stabilize, highlight Accept

Ammonium, Nitrate, and Chloride sensors can be used on 60510-X, 6051020-X,
6051030-X, 6051010-X, and Quatro cables. these cables also accommodate pH
and oRP sensors so instrument setup is important.
WARNING: Ammonium, Nitrate, and Chloride sensors
should only be used at DEPTHS OF LESS THAN 55 FEET
i
(17 METERS). Use of the sensors at greater depths is
likely to permanently damage the sensor membrane.
WARNING: Ammonium, Nitrate, and Chloride
i
sensors should only be used in FRESHWATER.
SEtUP - AMMoNIUM, NItRAtE, CHLoRIDE
Install the Ammonium, Nitrate, or Chloride sensor in Port 2 if using in
conjunction with pH or oRP sensor on a 6051010 or Quatro cable. See the
Getting Started Setup section of this manual for a complete list of cable/sensor
configurations.
Press Sensor , highlight Setup, press enter. Highlight ISE1 if using an
ammonium, nitrate, or chloride sensor on a 60510, 6051020, or 6051030 cable.
If using a 6051010 or Quatro cable highlight ISE1 if the sensor is installed in
Port 1 or highlight ISE2 if the sensor is installed in Port 2. Press enter.
