Rpm Tachometer (#2)
If selected operating mode is rpm tachometer (tACH), the displayed routine after pressing
ENTER will be the one on the left.
First thing to configure is the number of pulses per revolution that provides the sensor
PPr
connected to the input. After "PPr" indication, display shows four digits (by default 0060) and
the possibility to enter the number that must be between 0001 and 9999.
When pressing ENTER again, display shows "dECP" an then "0000." to locate decimal point

position. It is possible to choose one decimal position or simply no decimal point by pressing
SHIFT key.
This operating mode always implies a rpm (revolutions per minute) reading and display scaling

EXAMPLE OF CONFIGURATION:
It is desired to measure the speed in m/s of a conveyor belt which is driven by a shaft turning at 300 rpm that has 20 cm of diameter and
provides 4 pulses per revolution.
In 1 second the shaft will generate 20 pulses (300 rpm = 5 rev/s and each revolution provides 4 pulses). Input frequency is then 20Hz. Belt
lineal speed is 3.142 m/s (v = e/t; v = 5 rev x
Direct proportional variation (dir) ; "FrEC": 0020 ; (no decimal point) ; "diSP": 3142 ; decimal point: 3.142

If selected operating mode is rate tachometer (rAtE), the displayed
routine after pressing ENTER will be the one on the left.
First thing to configure is the relation between display reading and the number of
pulses per second received at the input (input frequency). If increasing frequency
must result in an increasing display then "dir" (direct proportional variation) must be
selected. Select "inV" (reverse proportional variation) if increasing frequency must
result in a decreasing display or vice-versa. Select desired variation using SHIFT key
an then press ENTER.
Next action then is to define display scaling in four steps. Display shows "FrEC" and
then the number of pulses per second at the input must be introduced using UP and
SHIFT keys (1000 by default). Press ENTER to accept input frequency value.
Next step defines decimal point position using SHIFT key. Frequency resolution can
be configured with two (hundredths of a Hertz), one (tenths of a Hertz) or without
decimal places (Hz). Press ENTER to validate decimal point position.
Third step begins with "diSP" message and then a four-digit number which will be the
desired display that will correspond to the input frequency value 'FrEC' previously
configured in first step. Once it is entered (1000 by default) press ENTER to accept.
Last step defines display decimal point position. Choose desired location using SHIFT
key and press again ENTER to save changes and to return back to RUN mode.
