05
Review And Disconnect Safely
Compare results with the service procedure, close valves, reduce high-side pressure to a safe point and disconnect in the prescribed order.
安全性和相容性
Verify Refrigerant, Couplers, Hoses, and Pressure
Gauge Pressure Only
Interpret LM150 readings as gauge pressure and stay within -101 kPa to 6 MPa measurement coverage.
Hose Rating Can Govern
Standard hoses are listed for 600 PSI working pressure; 3000 PSI is a burst value, not a service target.
Check Hose Ends And Seals
Incorrect core orientation or worn nylon pads can prevent filling or cause leakage.
Use PPE And Ventilation
Wear appropriate protection, ventilate the area and avoid hazardous heat, humidity, ignition and electromagnetic conditions.
Use Known Refrigerant Data
Select the known refrigerant before interpreting readings or charging.
Restricted Operating Environments
Do not use or store the device in high temperature, high humidity, flammable, explosive, or strong electromagnetic field environments.
No Circuit Modifications
Do not modify the internal circuit. Unauthorized modification may damage the instrument or create hazards.
Inspect Service Connections
Inspect pipe fittings, hoses, hose terminals, and valve stems before testing. Replace damaged parts before use.
Release Pressure Before Disconnecting
Do not remove the high-pressure valve connection until the pressure drops to a safe point.
Follow System Charging Procedures
Different equipment and refrigerants may require different filling procedures. Follow the refrigeration system service requirements before charging.
Maximum Device Pressure
The maximum device pressure / overload limit is 10 MPa / 100 bar. This is not the normal measuring range and does not permit exceeding the rated pressure of the tested system.
檢測結果
Interpret Pressure, Temperature, SH, and SC
Read Pressure and Temperature Together
Interpret high- and low-side pressure together with T1/T2 temperature values, the known refrigerant, and operating condition.
SH/SC Validity
Requires correct refrigerant selection and stable full clamp contact.
Retention Change
Recheck hoses, pads, fittings and valve stems before moving to a separate leak-location procedure.
Post-Service Readings
Abnormal pressure or cooling can require additional electrical, mechanical, airflow or leak diagnosis.

常見問題
Refrigerant Library and Clamp Questions
什麼是 AUTOOL LM150 Used For?
LM150 is a digital manifold pressure tester for HVAC installation, refrigeration equipment testing and maintenance, automotive A/C service, air conditioners, and cold storage systems. It supports dual pressure testing, dual temperature testing, refrigerant service, vacuum measurement, and pressure leak testing.
- High/low gauge pressure, relative vacuum and two pipe temperatures; it also supports timed retention and selected-refrigerant calculations.
How many refrigerants are stored?
LM150 lists 93 refrigerants in its NIST-standard reference database.
Are Temperature Clamps Included?
Yes. LM150 includes two wired clip-on temperature probes. Connect them to the T1 and T2 sockets with full pipe contact for real-time temperature readings.
Does LM150 identify refrigerant?
No. Select only refrigerant already confirmed from vehicle/equipment information.
Can it locate a leak?
No. Pressure change can flag a problem; use an approved separate method to locate it.
Why Might Refrigerant Filling Fail?
The refrigeration system inlet has a valve core. When connecting hoses, pay attention to both hose terminals: connect the terminal with a core to the refrigeration system and the terminal without a core to the instrument.
- Check hose-end valve-core orientation, then inspect seals, fittings and valves and follow the connection procedure.
What Is The Standard Hose Pressure Limit?
The maximum working pressure of the standard hose is 600PSI, approximately 4.13MPa / 41.3bar. The hose burst pressure is 3000PSI, approximately 20.68MPa / 206.8bar. If the included hose does not meet your pressure requirement, use a suitable replacement hose.
- Use the lowest system, gauge and hose working rating. Do not treat the 100 bar instrument limit or 3000 PSI hose burst value as normal operation.
What powers it?
Four 1.5 V AA/LR6 batteries.
How does it differ from LM160?
LM150 provides the core 93-refrigerant dual-clamp manifold workflow; LM160 adds program control, eight languages and a 95-refrigerant database.
Is The Pressure Reading Gauge Pressure Or Absolute Pressure?
The LM150 pressure reading is gauge pressure. Confirm whether the system procedure requires gauge pressure or another pressure reference before interpreting test data.
What Is The LM150 Pressure Test Range?
The overall pressure and vacuum coverage is -101 kPa to 6 MPa, approximately -1.01 bar to 60 bar. The pressure test range is 0 kPa to 6000 kPa, and the vacuum test range is -101 kPa to 0 kPa. Do not use it beyond the measuring range of the instrument.
How Many Refrigerants Does LM150 Support?
LM150 includes a built-in 93-refrigerant NIST-standard database. Confirm that your required refrigerant is included before ordering.
What Power Supply Does LM150 Need?
LM150 uses 4 × 1.5V AA / LR6 batteries. If the low-power sign appears, replace the batteries as required to avoid affecting normal use.
What Should I Check Before Testing?
Check the rated pressure of the tested equipment, confirm that the system does not exceed the instrument range, inspect pipe fittings and hoses, replace damaged parts immediately, wear approved protective equipment, and work in a well-ventilated area.
What Are Common Leak Points To Check?
Check hose terminals, nylon pads, pipe fittings, hoses, valve stems, and refrigeration system pipes and connectors. Hose terminal nylon pads have a limited service life, and overuse or damage may cause leakage. Tighten the copper plug screw on the middle refrigerant inlet before or after operation as required.
LM150 和 LM160 有什麼不同？
LM150 supports vacuuming mode, refrigerant mode, pressure leak testing, 93 refrigerants, high/low pressure valves, two wired temperature clamps, a foldable hook, and a refrigerant sight window. LM160 adds program control, 8 interface languages, a 95-refrigerant database, and two-side handrails; choose it when those functions are required.

Very nice manifold set.
優點：
1. LCD read out means no more bouncy gauges and guess work.
2. Takes 2 batteries – easy enough.
3. Materials are heavy duty and the unit appears very well made.
4. Reads low and high pressure side.
5. Worked with my vacuum pump and filling setup – required same adapters most require.
缺點：
1. Something this nice deserves a nice storage case to protect it – most people will just leave it hanging up though.
