P
ulsemeter Scale
The pulsemeter function measures human respiration or pulse rate. The wearer can
simply read off the correct respiration / pulse per minute by counting the time needed for
the listed number of pulsations.
Description of Operation
The Pulsemeter scale simplifies the measure of pulse by allowing the wearer to directly
record the pulsation rate. Instead of counting the pulses over a short period of time,
simply count the pulsations & stop the timer. The pulsemeter scale then displays the
exact pulse rate.
The original
Trainmaster Pulsemeter
is marked "Graduated for 30 Pulsations." If after
the 30th pulse, the operator stops the chronograph counter at 20 seconds, reading from
the stopped second hand on the pulsemeter scale will result in a pulsation rate of 90 beats
per minute. The pulsation scale can be used to measure any type of repetitive action, by
simply measuring 30 units of the action.
The
Trainmaster Pulsemeter Pro
and limited edition
Trainmaster Doctor's
Chronograph
are configured for measurement of 15 Pulsations only. Combined with the
single-button chronograph to allow for quicker measurement of pulse and respiration
rates, the 15-pulse scale also minimizes human error due to reaction time to ensure a
more accurate reading.
T
achymeter Scale
To compute the speed of a car over a certain distance, reset the chronograph second hand
to zero position, then press the top chronograph button P1 to start timing. At the end of
the fixed distance, press the button again. If the time elapsed is 45 seconds, the second
hand should point to the figure 80 on the Tachymeter scale. If the fixed distance is a
kilometer then the car is traveling 80 kilometers per hour. If the distance covered is a
mile, then the speed is indicated in miles per hour, in this example 80 MPH.
The inner spiral of the
Trainmaster Pulsemeter
is a tachymetric scale capable of
measuring elapsed time of up to 3 minutes. If for example, the time elapsed is 1 minute
30 seconds, the second hand will point to the figure 40 on the 2nd ring of the Tachymeter
scale. Over a distance of 1 mile, the car is thus traveling at 40MPH.
The limited edition
Fireman Skylab
has a tachymeter scale on the outer bezel for
measurement of elapsed times up to 1 minute.
