2.4.1 Fluorometers 2.4.1.1 Safety Statement A Valeport Fluorometer is classified as Risk Group 1 under standard 62471. As the type is classified as Risk Group 1 solely due to radiation in the visible band a hazard label is not required. - Page 6 LED power, sample volume and optical path length). Valeport Fluorometers have a calibrated linear response for 2 gain settings (e.g. the ranges 0-40 µg/l (G5) and 0-800 µg/l (G1) for chlorophyll a). At higher concentrations, unlike analogue devices which generally flat-line at full-scale deflection (e.g.

By altering the angle of the target the magnitude of the reading should change thereby showing the correct operation of the sensor. If the test target is not available then use a piece of good quality white paper. © 2021 – Valeport Ltd Page | 6... -
Page 9: Data Acquisition
: MANUAL-2034990662-4 | issue: 1.0 3 Data Acquisition The fastCTD uses the concept of distributed processing, where each sensor has its own microprocessor controlling sampling and calibration of readings. Each of these processors is then controlled by a central processor, which issues global commands and handles all the data. This means that all data is sampled at precisely the same instant, giving superior quality profile data. -

Page 19: Operation
6.1 Switch Cap Logger Pack Operation If the fastCTD is supplied with a standard logger pack and connector, it will be also supplied with a SubConn Switch Cap. This is a dummy connector plug has pins 1 & 10 linked. Inserting the switch cap into the instrument connector activates the instrument and it will begin logging data in the last configured mode. -
Page 20: Cabled Operation
6.3 Cabled Operation If the fastCTD is supplied with a standard logger pack, it will be also supplied with a 3m Y lead. Connecting the Y-lead to the instrument will switch the fastCTD on, where it can be configured via the DB9 connector attached to a PC serial port. -
Page 21: Memory
: MANUAL-2034990662-4 | issue: 1.0 7 Memory The fastCTD is fitted with a solid state non-volatile Flash memory, capable of storing over 10 million lines of data (equivalent to 10,000 profiles to 500m at 1m profile resolution). -
