1-2 BenchMike Pro 2025/2050 & Z-Mike Pro 4025/4050 Instruction Handbook: Introduction
1.2 Calibration
Each BenchMike Pro is calibrated at the factory using specialized NDC Technologies equipment. This calibration
is performed with N.I.S.T. (National Institute of Standards and Technology) traceable calibration gauges in an en-
vironmentally-controlled laboratory to ensure optimal performance.
Before a certificate of calibration is issued, each of the following procedures is performed at the factory:

External optics are cleaned

Internal optics are cleaned

Multiple mastered points are used to enhance accuracy

Test points and power supply voltages are verified

Optics are aligned

Scan-across test is performed to verify accuracy at several hundred points

Repeatability test is performed to determine short-term measurement stability

Drift test is performed to determine long-term measurement stability

Multi-point performance test is performed with a V-block
In order to ensure the measurement accuracy shown in the Specifications , it is recommended that you have your
BenchMike Pro calibrated by NDC Technologies once per year. While at the factory, NDC Technologies can also
perform any required retrofits, repairs, or upgrades.
1.3 Using the BenchMike Pro
To turn on the BenchMike Pro, push the power button on the rear of the
unit. It will take about one minute for the unit to initialize.
To turn off the BenchMike Pro, push the power button for one second.
The BenchMike Pro will begin the power-down cycle. Holding down the
power button for five seconds will immediately turn off the unit.
When the BenchMike Pro is turned on, the last saved configuration is
displayed on the touch screen. The graphical user interface includes a touch screen which allows the screen to be
used to select items. Use your finger to select commands, menus, help, or enter numbers.
To avoid scratching the coating on the touch screen, do not use any sharp object on the display. Remember to
clean the screen regularly, using a household window cleaner. Ensure that the lower rim of the screen is kept
clean of dust and other contaminants to avoid degrading the gasket around the display.
