What does OL mean on fieldpiece gauges?
Over range: “OL” or “-OL” is displayed. Operating environment:32°F to 122°F (0°C to 50°C) at <75% RH.
Are fieldpiece digital gauges waterproof?
The heavy duty casing, reinforced hook, water resistant, impact resistant screen, strategically placed thermocouple ports, and hermetically sealed sight glass, all ensure the SMANs are ready to withstand the rigors of field use.
How long do AC gauges last?
As a general rule of thumb, you can expect your AC low pressure hoses to last about eight years, and likely no more than ten. And the older they get, the more likely they are to leak. If they do, your engine can overheat, and you could end up with expensive repairs.
How do I calibrate my sman460 temperature thermocouples?
To calibrate your SMAN460 temperature thermocouples, adjust the pot on the front of the meter labeled SLT Cal or LLT Cal. The best way to calibrate is to match to a known temperature. Ice water is very close to 32°F and is readily available. Accuracies of one degree or better are obtained through field calibration.
How does the SMAN work?
Your SMAN combines high pressure manifold gauges, a superheat/subcooling calculator, micron gauge for vacuum (SMAN3), and dual temperature measurements into one easy-to-use instrument. Your SMAN calculates and displays target superheat and actual superheat to ensure proper charging of a unit.
How do you pull a vacuum from a sman460?
Pulling a Vacuum Follow all manufacturers’ evacuation procedures over those in this manual. 1 Connect your SMAN460 to your vacuum pump and the system, then power on your SMAN460. 2 Set up vacuum alarms. These will notify you when you’ve reached your desired vacuum and stabilization levels.
How do I Reset my SMAN to normal settings?
1 Hold the ALARM button for one second to enter Alarm Set mode. 2 Press the ALARM button to toggle between Alarm Hi and Lo. 3 Use ARROW button to select the value and press ENTER to lock in each digit. Once last digit in Alarm Lo is locked, your SMAN will automatically revert to normal testing mode.
