Preparation for use
Prepare the probe for use before calibration or sample measurement.
1. Twist and remove the soaker bottle from the lid to release the pressure.
2. Remove the soaker bottle lid from the probe.
3. Rinse the probe with deionized water. Blot dry with a lint-free cloth. Do not touch the
tip of the probe.
4. Get a single membrane module from the shipping package. Do not touch the
membrane surface.
5. Add 12 drops (0.5 mL) of the Ammonia probe filling solution in the membrane
module.
6. Install the membrane module on the probe and tighten. Do not spill the filling solution.
Calibration
Before calibration:
The probe must have the correct service-life time stamp. Set the date and time in the meter before the probe is attached.
It is not necessary to recalibrate when moving a calibrated probe from one HQd meter to another if the additional meter is
configured to use the same calibration options.
Default calibration standard set for ISENH3181 probe requires 1, 10 and 100 mg/L Ammonia standard solutions. A new
method can be made if custom calibration or measurement settings are needed. Refer to
Advanced operation on page 7
for a list of additional calibration sets.
To view the current calibration, push , select View Probe Data, then select View Current Calibration.
If any two probes are connected, push the UP or DOWN arrow to change to the single display mode in order to show the
Calibrate option.
Make sure the Ammonia membrane module is assembled with the correct amount of Ammonia fill solution.
Prepare the probe for use (refer to Preparation for use on page 2).
