Metric and imperial convertible, measuring range: 1"-2" (25-50mm), resolution: 0.00005" (0.001mm)
Coolant Proof Micrometer Series 293 - Meets IP65 Dust/Water Protection Standards
Features: • Meet the IP65 protection standard, and can be used in various environments, such as being exposed to cutting oil and other environments. After use, anti-corrosion treatment is required. • With measurement data output function, with waterproof connection cable. • All plastic components are made of oil-resistant materials. • ±1μm accuracy (for models with measuring ranges up to 75mm). • Automatic power on/off function. • With inspection certificate (for models with a measuring range below 50mm) * This model cannot be used to obtain a calibration certificate.
Technical Parameters Accuracy: See performance parameters (excluding quantization deviation) Resolution: 0.001mm, .00005"/0.001mm (less than 4") or .0001"/0.001mm (greater than 4") Flatness: 0.3μm Parallelism: The measuring range is less than 50mm, the measuring range is 1 μm, the measuring range is less than 100mm, the measuring range is 2 μm, the measuring range is less than 175mm, the measuring range is 3 μm, the measuring range is less than 275mm, the measuring range is 4 μm, the measuring range is greater than 300mm, and the measuring range is 5 μm. pcs), 938882 battery life: about 1.2 years under normal use (8 months for models with a measuring range greater than 100mm) dust/water protection level: up to IP65 protection standard Automatic power on/off, data hold, data output, inch/metric conversion (inch/metric type) warning: low voltage, calculation error
Function
Origin setting (ABS absolute measuring system):
Press the origin button to reset the ABS origin at the current micrometer screw position. Depending on the size, the origin value can be set.
Zero point setting (INC incremental measurement system) Short press the ZERO/ABS button, the display is set to zero at the current micrometer screw position, switch to incremental measurement mode, and long press the button to reset to ABS measurement mode.
Data retention:
The displayed value can be kept. If this function is released, the previously set zero position or the measured value from the origin position will be displayed
Comes in handy for position measurement where the display is not easy to see.
Measurement data output*4:
With measurement data output terminals, statistical process control systems and metering systems can be established 4: MDC-MX/MXT/MJB only
Automatic Power On/Off:
If it is not used for about 20 minutes, the LCD display will disappear, but the origin (preset value) of the ABS measurement length series is still in memory
state. Rotate the micrometer screw again to restore the display.
Error alert:
In case of overflow or calculation error in the display, an error message will be displayed on the display, and the measurement function will automatically stop. in error state
Measurement cannot be continued. In addition, when the battery voltage is low, the battery mark will light up before entering the state that cannot be measured, to indicate that the battery will
To be exhausted.
Function lock:
In order to prevent changing the origin position due to misoperation, the PRESET (origin setting) function and ZERO (zero adjustment) function can be locked.
