DCP Microsense Logit Quick Start Manual

Problems? - please check the following:
❏ No pulse output being shown in 'real-time' display:
Check transmitter working using the watch - if not replace transmitter battery.
If OK move LogIT receiver nearer to transmitter. Check LogIT battery.
❏ Sudden increases of heart rate (spikes) shown:
Receiver has picked up interference from nearby equipment or been knocked
causing extra pulse(s). Adjust position of LogIT/Receiver.
❏ Occasional loss of results:
Transmitter strap too loose or requires better skin conduction (see below).
Transmitting distance too far - replace transmitter battery or move receiver nearer.
Important information
The watch may also be worn to check transmitter and monitor pulses live but it will not
necessarily indicate correct reception by the Heart receiver.
If required the Heart Receiver can be used a short distance away from LogIT using a
single Microsense extension cable. This allows it to be more easily placed on the
body (eg in a top track suit pocket) next to the Polar etc. Heart Transmitter. Note that
if the subject being monitored is not doing strenuous exercise there may be
insufficient body sweat to allow good conduction between the skin & the two
transmitter conductive belt pads. Special conductive gel's available from some
chemists will improve conductivity (eg 'Dracard' electrode gel, K-Y gel) or you can
make up a saline solution. Smear a small amount of gel on each pad but TAKE CARE
NOT TO SHORT THE TWO PADS OUT WITH THE GEL OR THIS WILL PREVENT
RELIABLE OPERATION.
Other sensors may be plugged into LogIT at the same time as the heart receiver (for
example a temperature probe to monitor skin temperature) and general purpose
software will display their results as well as the pulse rate.

How the system works
The POLAR (or equivalent) system works by detecting and amplifying the small
electrical heart signals through the skin using two conductive rubber pads and then
transmitting a pulse to a receiver using a short range low frequency signal. The LogIT
Heart Receiver is a miniature version of the watch which receives the signal and
converts it into a form which LogIT can use to show and log results. As the
instructions supplied with your POLAR system points out, it works on a frequency
which makes the watch (and the LogIT Heart Receiver) also sensitive to physical
knocks and electrical interference from other equipment, especially television
monitors. The LogIT Heart receiver contains circuitry which helps to reduce the
effect of nearby equipment and also restricts the reception direction range, but you
should always keep as far as possible from electrical equipment (Minimum 1.5
metres) & avoid knocking the receiver.
