Connecting an AQUAPROBE
To connect the Aquaprobe to the Aquameter, 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.
Switching On
To switch the meter on or off, briefly press the red key. If you do not press any keys for thirty minutes,
the meter will automatically switch off. 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).
Taking Measurements
If the AQUAPROBE you are using includes a pH/ORP electrode, remove the storage cap by pulling the
red lanyard straight down. Do not use a twisting motion. Fit the protective Sleeve Cap into the open
end of the 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.
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. 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. WARNING If the AQUAPROBE you
are using includes a pH/ORP electrode, remember to remove the protective Sleeve Cap and replace
the pH/ORP storage cap after use. Failure to do so will damage the electrode.
Choosing the displayed units
The AQUAMETER only displays one set of units per parameter, e.g. either DO% or DOmg/l. To alter the
way the AQUAMETER displays readings, press the MENU key, choose Settings then Units. On the Units
Menu screen, select the reading you want to alter from the list then use the up/down arrow keys to
alter the settings. For more details, refer to the full instruction manual. If you are logging data on the
meter all readings are recorded.
Trend Indication
To the right of each reading, a trend indication is given. This consists of either an upwards facing arrow
(which indicates the value of the reading is rising), a downwards facing arrow (which indicates the
value of the reading is falling) or a two-headed arrow which indicates a steady reading. Gently stir
the Probe in the sample until the temperature reading is steady. By this time the other values should
be reasonably steady and ready for saving.
