5. Connecting an Aquaprobe
The Aquameter is designed to operate in conjunction with any one of eight different
Aquaprobes (each variant is considered in later sections).
To connect an Aquaprobe, align the key slot of the Aquaprobe plug with the Aquameter
socket, then press the plug into the socket and tighten the retaining collar.
Always ensure
the Aquameter is switched off prior to connecting or disconnecting an Aquaprobe
.
6. Taking Measurements
If the Aquaprobe you are using includes a pH/ORP electrode, remove the storage cap by
pulling the red lanyard marked ‘Remove Before Use / Replace After Use’ straight down.
Do
not use a twisting motion to remove or replace the cap as this can unscrew the
electrode from the Probe body.
Rinse any salty deposits from the pH/ORP electrode with
fresh water.
Fit the protective Sleeve End Cap into the end of the Probe sleeve if required, then
immerse the Aquaprobe in the sample water, making sure that the water level covers the
minimum immersion depth groove halfway up the Probe sleeve. Switch the Aquameter on.
TIP:
Occasional application of a smear of silicone grease or similar lubricant to the
protective Sleeve End Cap O ring and the inside rim of the Probe sleeve will make fitting
and removal of the Cap easier.
If the Aquaprobe is connected correctly, the meter will read the Probe’s serial number and
model number, then will automatically configure itself to display only those readings the
current Aquaprobe is capable of taking. Initial Probe readings will be displayed on the
meter’s screen along with the current GPS status (GPS model only). The initial data screen
for the GPS Aquameter in conjunction with the fully loaded AP-800 Aquaprobe is shown
below.

If the current Aquaprobe / Aquameter combination is capable of reading more than three
parameters, left/right arrows will appear at the bottom corners of the screen to indicate
further data screens are available (as shown above).
To access these screens, simply press either the left or right arrow keys. Any value that is
out of range or unavailable will be displayed as dashes. The other three screens available
with the AM-200/AP-800 combination are shown below.
