Portable Micro-Pressure Pump Handheld Low-Range Air Pressure Tester & Calibrator -90 to 600kPa

Features:
This portable micro-pressure pump is a handheld, manual pressure source designed for precise testing and calibration of pressure instruments
It generates both positive pressure and vacuum (negative pressure) with high adjustment resolution
Ideal for calibrating pressure gauges, sensors, and other instruments using clean air
Its compact and lightweight design makes it perfect for on-site use

Installation & Operation:
1. Pressure Calibration (Gauge Mode Example)
* Connect the device under test (DUT) to the DUT output port and the reference standard gauge to the standard gauge output port
* Rotate the fine adjustment pump counterclockwise to its starting position. Set the micro-adjustment knob to the mid-position
* Ensure the pressure release valve is fully closed
* Slowly rotate the fine adjustment handwheel clockwise to increase pressure until the desired calibration point is approached
* Use the micro-adjustment knob for precise fine-tuning to the exact pressure point
* To release pressure after calibration, open the pressure release valve
2. Vacuum Calibration
* Connect the device under test (DUT) to the DUT output port and the reference standard gauge to the standard gauge output port
* Rotate the fine adjustment pump clockwise to its starting position. Set the micro-adjustment knob to the mid-position
* Ensure the pressure release valve is fully closed
* Slowly rotate the fine adjustment handwheel counterclockwise to generate vacuum until the desired calibration point is approached
* Use the micro-adjustment knob for precise fine-tuning to the exact vacuum point
* To release vacuum after calibration, open the pressure release valve
