The counting function can be used to measure directly in metres, feet or number of pulses. This means it is possible to measure a motor s rotation speed, the pulse frequency or the contact opening time of a relay with the same instrument. One key, one function (The functions indicated in italics are only available on the C.A 1727) When an object s speed is irregular, it may prove necessary to apply smoothing to the measurement. This function computes a sliding average of the last 10 measurements. This makes it easier to read. The MIN / MAX function does your work Pressing this key locks the digital display for you. Vary the load on a motor on the last measurement. The analogue and let the tachometer record display continues to show the real-time the variations on its own measurement. The count function allows you to Two thresholds (high and low) measure the number of revolutions, can be programmed on each unit. metres or pulses directly. The instrument indicates when they are overrun by sounding a buzzer and displaying a visual symbol This key can be used to switch This key can be used to record the value the C.A 1727 to programming mode. displayed. It no longer performs any measurements, When the Scan function is programmed, the bargraph is deactivated, For some applications, the measurement you can press this key to start and the optical transmitter is shut down. range has to be locked. The analogue scale the measurement recording cycle The key functions become those then remains fixed throughout according to the interval programmed. indicated in yellow. the measurement. Particularly easy to read The display is the control panel for the instrument. At a glance, you can use it to check that the operating conditions are satisfactory: confirmation of infrared signal transmission and reception, alarm thresholds activated, etc. All the functions activated are clearly indi- cated. A 42-segment bargraph is available in addition to the digital display.
