No credit indication Continuous yellow LED.
1 Performance specification is tested at a standard test velocity of 480 mm/min (18.9 in/min) with a 50 mm (1.97 in) stylus
Significantly higher velocity is possible depending on application requirements.
2 Trigger force, which is critical in some applications, is the force exerted on the component by the stylus when the probe
triggers. The maximum force applied will occur after the trigger point (for example overtravel). The force value depends on
related variables including measuring speed, machine deceleration and latency.
3 These are the factory settings; manual adjustment is not possible.
Typical battery life
Battery type Standby life 5% usage (72 minutes/day) Continuous use
CR2 lithium manganese dioxide 270 days 75 days 155 hours
½ AA lithium-thionyl chloride 410 days 125 days 260 hours
