PC Software bbe++ supports the BenthoTorch.

First version
Please Note:
Decimal points are according to local settings of Windows, i.e. internationally, the decimal point is “ .” but in
most of Europe it is „ ,“. Please pay attention to this. Most import/export difficulties are caused by the use of the
“point” or “comma” and vice versa. The software screenshots contain “decimal commas”, i.e. the European
system.

General Safety Precautions
bbe BenthoTorch Manual Page 7
General Safety Precautions
The bbe BenthoTorch is an instrument for determination of the concentration of chlorophyll on surfacees or on
the ground of a water body. It should only be used for this purpose.
Only instructed staff should operate this instrument.
Consult appropriate safety manual in case of using hazardous compounds and solutions. Wear gloves, coat and
safety goggles.
Electrical connection of the instrument should only be carried out by trained staff.
The instrument should only be opened by authorised staff.
Changes to electrical connections and circuits may cause damage to the instrument and lead to loss of warranty.
Cleaning the instrument:
The instrument should be cleaned after use. The use of aggressive cleaning fluids or water at high pressure
should be avoided. Neither should any mechanical cleaners or apparatus come into contact with the sensor
head or LED display. Attention: in order to obtain exact measurement results, the measuring head should be
free from grease.
Before stowing the instruments should be cleaned of dirt under running water. If necessary, normal,
commercially available washing up liquid can be used. Rub the instrument dry with a soft cloth and take care
when drying the electrical contacts.
The simplest way to store the instrument for any length of time is in its original case, in which the accessories
can also be stored and kept dry.
Supplement to the safety instructions
Performing electrical connection may only be carried out by trained personnel. Maintenance, such as e.g.
exchanging the rechargeable battery pack, may only be carried out by personnel trained and authorised by bbe
Moldaenke. Replacement parts and repair materials must be issued/released by bbe Moldaenke for each case.

Quick start instructions
bbe BenthoTorch Manual Page 8
Quick start instructions
1. Charge the BenthoTorch by using the power supply connected to the small cable housing of the USB cable
2. Start the BenthoTorch by turning it upside down and back again in one quick movement.
If the BenthoTorch is equipped with a reed contact to switch it on with a magnet, a symbol is printed on the
label of the BenthoTorch. Please tip on the symbol with the magnet to switch the BenthoTorch on. The
magnetic switch can be used alternatively to the shaking switch.
3. Use a wrist strap to secure the instrument
4. Ensure that the connector is closed with the cap
5. Go to “Start measurement”
6. Apply the BenthoTorch to the benthic algae. Ensure that the red foam shadows the algae from the light.
Tip this point
with a magnet to
start the
BenthoTorch

7. If there is an internal GPS module available and activated, the status of the GPS signal is shown. If the given
quality criteria are met, the measurement starts automatically, otherwise, the poor positioning information can
be used (takepos) or the GPS information can be skipped.
PosFix Num Quali
YES 4 95%
takepos. skip
If there is no GPS signal e.g. within buildings only “skip” is available.
8. During the internal calibration a decreasing number of # is shown

The end of the measurement is signalled by a short vibration. The result can be read from the display. The
results of 3 algae classes are shown alternating.
