VGW760 Elitech

Features:

- Brand new Vacuum Gauge: Used for system leakage testing and discern vacuum pump quality of the evacuation in an HVAC and refrigeration system; accurate measurements from 19,000 Microns (atmosphere) to 0 Micron.
- Free App (iOS and Android): Settable high/low-pressure alarm, you can receive remote notifications when readings move beyond a predetermined value. The data could be recorded and exported in Excel and PDF format.
- Long Transmission Distance: Elitech Pressure Gauge App is connected by wireless technology, up to 1187' in ideal conditions (no obstructions).
- Rubberized water-resistant housing (IP65 Rated); ensure a deep vacuum throughout the entire system and prevent the mist when the refrigerant caused by refrigerant bottle blasting.
- Multiple units:  Easy conversion between 8 measurement units: inHg, Torr, psi, mbar, mTorr, Pa, micron, Kpa.

Operation Instruction
1 )Press to turn on the gauge before connecting it to a system. It will take 10 seconds for the gauge to warm up. Then it enters normal display.
2) After power on, the gauge will display "----" if the current pressure goes above its measuring range. Data does not show until the measured pressure is within the range.
Note: Keep the pressure below 27.5 bar, to avoid damage the sensor.
3) Make sure the connection type of the access system matches with the gauge fittings. If not please use the included adapter.
4) Press and release the light button to turn on the backlight. The backlight will be auto off two minutes later. 
5) Press and hold the light button to switch measurement units.
6 ) Press and release the wireless button to enable wireless connection. Press it again to disable wireless connection.
7) Press and hold the wireless button until "REC" appears in the screen to enable record function. Press and hold the wireless button again to disable this function.
8) Press and release the power button to turn off the gauge. Please use special tools to remove it.
Note: Please do not close the vacuum pump before removing the vacuum gauge from the system, or high pressure may occur in the system so that impurities will enter the sensor cavity.

Clean the sensor: 
The vacuum sensor may be contaminated by impurities in use. To ensure its accuracy, please follow the steps as follows:
1) Turn the gauge off and remove batteries
2) Inject acetone or alcohol (>70%) into the vacuum cavity with a dropper or a syringe. Tighten the nut and gently shake the gauge.
3) Loosen the nut and drain the fluid from the cavity. Repeat such operation 3 to 4 times.
4) Evacuate it or place it for 3 hours until the sensor gets dry.

Warning:
1. Please use the gauge in specified environment to avoid error or damage of the sensor.
2. Please do not use chemical solvent or corrosive liquid to clean the gauge.
3. Please do not disassemble the gauge.
4. Remove the batteries if the gauge is not to be used for a long time in case the leakage corrodes the gauge. The batteries included are not rechargeable. please do not charge them.

Please use a special tool to install or disassemble it. Please do not rotate the shell forcefully to avoid damaged.
