TC86 - Plain prose fact, asked in the document's own words
Query: What is the recommended recalibration interval for the Tolvan A3?
Document: A10_tolvan_a3_product_overview.md, section Calibration
Reference answer: 22 months from the date of the last certificate
Decoy: A08_warranty_terms_sales_pack.pdf states a 36-month WARRANTY period for the Tolvan A3 - a different fact that must not be confused with the recalibration interval answer.

or nutrient-rich water are advised to shorten the interval between visits
rather than to clean the sensing face themselves, because the inductive cell is
easily damaged by an abrasive.

## Calibration

Every instrument leaves the laboratory with a signed certificate recording the
as-found and as-left bias at four reference points across the working range.
The recommended recalibration interval for the Tolvan A3 is 22 months from the date of the last
certificate. An instrument returned early because of a
suspected drift is checked as found before anything is adjusted, so that the
drift can be quantified rather than merely corrected.

## Firmware

Firmware is updated during a service visit rather than over the telemetry link,
because an interrupted update on a deployed instrument leaves it unreadable
until it is recovered. A customer who declines a recommended update is asked to
confirm in writing, and the confirmation is attached to the instrument record.

Extracted Text: # Tolvan A3 - product overview

The Tolvan A3 is a conductivity and temperature sensor built for
continuous deployment in estuarine and coastal water. It is the instrument most
of our customers meet first, and most of the questions the service desk answers
are about this one.

## What it measures

The instrument reports conductivity, temperature and a derived practical
salinity. Conductivity is measured with an inductive cell, which has no exposed
electrodes to foul or to wear, and temperature with a thermistor mounted in the
same flow path so that the two readings describe the same parcel of water.
Pressure is not measured; where a depth record is needed, the instrument is
paired with a separate pressure sensor on the same mooring.

## Where it is used

Typical deployments are estuary monitoring for a regulator, intake monitoring
for a water treatment works, and baseline surveys ahead of construction in a
harbour. It is rated for continuous immersion to fifty metres. Deeper work uses
the Tolvan C5, which shares the sensing arrangement in a
pressure housing rated considerably deeper.

## How it is powered and read

On a mooring, the instrument runs from an internal battery pack and logs to
internal memory. On a cabled installation it is powered over the same cable
that carries its data, and reports continuously to the Brannoc
telemetry gateway, which forwards to the customer's own system. The two modes
are configured at commissioning and are not switched in the field.

## Fouling and cleaning

In estuarine water the practical limit on deployment is biological fouling
rather than power or memory. An anti-fouling guard and a sacrificial anode are
fitted at commissioning and replaced at each service visit. Customers in warm
or nutrient-rich water are advised to shorten the interval between visits
rather than to clean the sensing face themselves, because the inductive cell is
easily damaged by an abrasive.

Warranty Terms
Service pack - warranty terms for the service desk
1. What is covered
These are the warranty terms the service desk applies when a customer reports a failure. They apply
to
every new Tolvan A3 supplied by Fenwake Instruments Ltd, however it was ordered and wherever it is
deployed.
The warranty covers the instrument, its pressure housing, its connector and any cable supplied with
it. It
covers failure arising from a defect in materials or workmanship. Where a covered failure occurs,
Fenwake repairs or exchanges the instrument at its own option and bears the cost of carriage in both
directions.
2. The warranty period
Every new Tolvan A3 carries a warranty of 36 months from the date the instrument is delivered. The
period runs from delivery rather than from commissioning, and is not extended by a repair carried
out
under it.
2.1 Instruments repaired under warranty
A repaired instrument carries the unexpired balance of the original period, or ninety days from the
return
of the repaired instrument, whichever ends later.
3. What is not covered
(cid:127) Fouling, corrosion of sacrificial components, and wear of consumables such as anodes,
guards and
gland kits.
(cid:127) Damage caused by a mooring failure, a vessel strike, a snagged cable or any other
mechanical event
outside the instrument.
(cid:127) Damage caused by opening the housing outside a Fenwake workshop, or by breaking a
calibration seal.
(cid:127) Drift within the published specification. Drift is a calibration matter, not a defect.
(cid:127) Any instrument whose serial number has been removed or altered.
4. Making a claim
A claim is made through the service desk, quoting the serial number and the delivery note. The
service
desk raises a ticket, arranges return carriage and tells the customer within five working days
whether the
failure is covered. Where it is not covered, the customer is quoted for the repair before any work
starts.
