How Values of the Settings Are Displayed
• The LED1 count indicates the sign of the value, plus (+) or minus (-). When LED1 is OFF this
indicates plus (+), when LED1 is ON this indicates minus (-).
• The LED2 count indicates the left digit (10's) of the 2-digit decimal value, the LED3 count indicates
the right digit (1 to 9) of the 2-digit decimal value. Flash duration: 300 ms
• For example, if LED2 flashes twice the LED3 flashes 4 times, this is read as "24". To adjust this
value to the actual reading: 24 x 0.1 mm = 2.4 mm where "2.4 mm" is the actual value.
• The LEDs remain ON for 2 sec. if the current value is "0".
• The LED2 and LED3 displays automatically alternate.
