Overview
The DB25-ES900 elevator speed limiter speed tester is a small, lightweight, battery-powered Handheld elevator speedometer produced by DUBAN brand. It is mainly used for elevator adjustment, maintenance and inspection work. The equipment includes two display channels and corresponding test modules.
Features
1. With data storage function, it can store 20 sets of data (including CH1 value, CH2 value, MAX Maximum), and can customize a larger storage capacity.
2. With MAX Maximum hold function.
3. With average calculation function, the average value of up to 200 measurement values can be calculated, and the measurement time interval is 10ms.
4. With battery low voltage prompt function.
5. With distance measurement function.
6. Support Bluetooth printer function, can directly print measurement data.
7. Support connecting with the computer through a USB data cable or Bluetooth adapter to realize data transmission.
Principle
The tester uses a contact test method to calculate speed, speed and distance by measuring pulse signals. Its core measurement module includes pulse output (set Electrode open output gate) and infrared Light Emitting Diode Illuminant. After detecting the pulse signal generated by swirl/spin or movement, and after internal processing (such as average calculation), the instantaneous value, linear velocity and other measurement results are output on the liquid crystal display.
Applications

Notice
• When measuring distance, please note that the measurement range is 0-999mm, and the numerical accuracy beyond 999mm to 5000mm cannot be guaranteed.
• The device will automatically shut down after 180 seconds of no-button operation.
• Please ensure that it is used within the operating temperature of 0~ 45 ° C and the operation humidity range of 35~ 85% RH (except condensation).
When storing, the temperature should be maintained at -10 to 60 degrees Celsius, and the humidity should be maintained at 35 to 85% RH (except for condensation).
Please note that the life of the bearing under the maximum load of the specification is 2x10 ^ 7 rpm-h.
• Please ensure that the battery is sufficient before use, and the device has a low voltage prompt function.
