CALIBRATION
• Use POWER button to turn on A/C Analyzer.
• From MAIN MENU press CAL button.
For Thermocouple Calibration
NOTE: Press F4 (EXIT) in Thermocouple Cal 1 Screen to
return to MAIN MENU without saving, or F2 (PT) to calibrate
the pressure transducer.
• Insert thermocouple into thermocouple socket.
• Place thermocouple at known temperature and allow
temperature to stabilize.
NOTE: Use crushed ice and just enough water to cover and
calibrate to 32˚F or 0˚C, or place thermocouple clamp on a
heavy wall copper pipe and clamp a calibrated meter next to
it.
• Use ► and ◄, buttons to highlight unit and ▲ and ▼
buttons to adjust unit value to input calibration temperature.
• Press
F1 (CAL) button.
• If thermocouple has correct reading, press F4 (EXIT) to
save.
• If thermocouple reading is off, Press
F1 (REDO) to redo the
calibration.
For Pressure Transducer Calibration
CAUTION: To calibrate the pressure transducer you will
need a source of high-pressure gas with a highly accurate
calibrated gauge. Do not start calibrating the pressure
transducer without it. For best results, calibrate sensor at
close to its maximum value.
NOTE: Press F4 (EXIT) in Pressure Transducer 1 and
Pressure Transducer 2 Screens to return to MAIN MENU
without saving, or F2 (TC) to calibrate the thermocouple.
• If in Thermocouple 1 screen, Press F2 (PT) button to
display Pressure Transducer 1 screen.
• Two pressures are required, one low and one high.
Atmospheric (0) is OK for the low pressure.
• With the pressure transducer at low pressure, use ► or ◄,
buttons to highlight unit and ▲ or ▼ buttons to adjust unit
value to input the low pressure.
• Press
F1 (NEXT).
• With the pressure transducer at the high pressure, use ►
or ◄, buttons to highlight unit and ▲ or ▼ buttons to adjust
unit value to input the high pressure.
• Press
F1 (CAL).
• If pressure transducer reading is correct, Press F4 (EXIT)
to save and return to MAIN MENU.
• If pressure transducer reading is off, press
F1 (REDO) to
redo the high pressure setting.
