Pressure test unit: Kpa; Mpa; bar; inHg; PSI.

Pressure test range: 0 Kpa 6000 Kpa. Pressure test resolution: 1 Kpa. Pressure test accuracy: +/- 0.5 %(FS)+ 5dgt. Pressure overload limit: 10000 Kpa (10 Mpa; 100 bar;). Vacuum test unit: Kpa; Mpa; bar; inHg; PSI.

Vacuum test range: -101 Kpa 0 Kpa. Vacuum test resolution: 1 Kpa. Temperature test unit: °C (Celsius), °F (Fahrenheit). Temperature test range: -40°C 150°C (-40°F 302°F).

Temperature test resolution: 0.1°C (-40°C 99.9°C), 1°C (100°C 150°C) 0.1°F (-40°F 99.9°F), 1°F (100°F 302°F). Temperature test accuracy: +/- 0.5 °C + 2dgt +/- 0.9 °F + 2dgt. Power Supply: 4 X 1.5V SIZE. 1x AUTOOL lm150 manifold gauge.

The temperature measured by the gauge is allowed to deviate by 3% from the actual temperature. The HVAC guage will read random numbers when it is powered on. You must press the ZERO key to clear the numbers after you power it on. The temperature probe of the temperature clamp is a silver metal part.

When testing the temperature, the silver metal must be in full contact with the object to be measured, or you can take out the silver metal to measure the temperature to make the test temperature accurate. Question 1: How to verify the accuracy of the temperature? Answer: Take out the black wire with the silver metal from the temperature clamp and put it in the boiling water. If the temperature is 100 degrees Celsius or the error is plus or minus 3%, it is normal. NOTE: Please pay attention to temperature unit conversion between Celsius/Fahrenheit.

Question 2: Does this gauge have a micron reading function? Answer: No, the accuracy of this refrigerant manifold gauge can only reach the accuracy equivalent to this unit: -101 Kpa-0 Kpa. Question 3: Why does the pressure value fluctuate slightly? Is it a leak or is the data inaccurate? Answer: According to the current level of hardware processing in the industry, it is difficult to achieve a 100% completely sealed valve on the market. The sealing degree of our guage hardware can only reach 99%. But these slight leaks will not affect the use. We are a professional worldwide Professional company.
