At the beginning of a pulsation, start the chronograph counter by pressing
push button [P1]. Press again when the 15 pulsations/respirations have been
recorded. If after the 15 pulses, the operator stops the chronograph counter
at 10 seconds, reading from the stopped second hand on the pulsemeter
scale will result in a pulsation rate of 90 beats per minute.
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.

Tachymeter: It computes speed over a given distance.
Please refer to the above instructions for
“Automatic Chronograph” to reset the
chronograph counter to zero position.
To compute the speed of a vehicule over a certain distance, press the top
chronograph button [P1] to start timing. At the end of the xed distance,
press the button again. If the time elapsed is 45 seconds, the second hand
should point to the gure 80 on the Tachymeter scale. If the xed distance
is one kilometer then the car is traveling 80 kilometers per hour.
The Fireman Skylab (CM1092), Fireman Storm Chaser (CM2092) and
Fireman Storm Chaser DLC (CM2192) have a tachymeter scale on the
outer bezel for measurement of elapsed times up to 1 minute.
The inner spiral of the Trainmaster Pulsemeter (CM1010) is a tachymeter
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
gure 40 on the 2nd ring of the Tachymeter scale. Over a distance of 1 mile,
the car is thus traveling at 40 miles per hour.
The wearer can nd the correct speed
per hour by recording the time needed
to travel a certain distance.
