3. Operations (continued)

3.2.6 PWM Time of Flight (TOF)

Time of Flight mode allows for the M-Series Tester to display the output of a PWM

ToF sensor. In a PWM ToF sensor the displacement amount is determined by the

time between the creation of the interrogation pulse an the

detection of the return pulse in the sensing element. This ToF calculation is depen-

dent on the velocity of the return pulse, sensor length, and the number

of recirculations performed by the sensor.

Recirculations:

When the M-Series Tester is in TOF-Mode, the tOF name on the display is followed by a hexadecimal value (0-F) which indicates the number of recirculations expec-

ted from the attached sensor. The default hexadecimal value for the mode is 0. The number of recirculations can be changed to accommodate the attached sensor

output.

Perform the steps below to reset the number of recirculations:

When 'tOF' displays on the screen, press and hold the 'B' button for 2 seconds.

The recirculation character (0-F) will begin to blink.

When the character is blinking:

Press „B" button to change the value. Repeat the procedure until the appropriate value displays. Then, press the 'A' button to return to the "tOF" measurement

mode.

Note:

In order to display millimeters a fixed value has been used for the location of

the null with respect to the sensing element. The M-Series Tester is setup for

the standard offset in the model MH and MS sensors. For all other models

there may be a shift in the output reading due to mechanical differences from

the MH and MS models. Please check with the factory for the offset on other

M-Series sensor models.

Note:

Once the 'A' button is pressed the desired recirculation value is saved in the

memory.

Note:

1. 'T0F0' denotes that there are no recirculations only the initial interrogation

pulse.

2. In the PWM TOF mode if the reported displacement is longer than 4 digits

the display will blink and only the most significant digits will be displayed.
