Accessory
Easy View Micron Gauge
Model SVG3
Measure the depth of the vacuum in microns
of mercury to verify all moisture and non-
condensibles have been removed from the
system. For the most accurate reading, connect
directly to a service port on the system or to a
Schrader core removal tool (illustrated below).
Calibration
Temperature
To calibrate your SMAN440 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 eld calibration.
1 Stabilize a large cup of ice water by stirring. Pure, distilled water
will be the most accurate.
2 Immerse the temp probe in ice water from SLT and adjust the
SLT Cal pot with a at head screwdriver and let it stabilize, keep
stirring.
3 Repeat Step 2 for temp probe in LLT.
Pressure Zeroing
To calibrate your SMAN440 pressure sensors
to atmospheric pressure, ensure that your
SMAN440 is disconnected from any pressure
source and at equilibrium with the ambient
pressure.
1 Press the CAL Atmospheric Pressure button and your SMAN440
will set the zero point of pressure to the ambient pressure.
Advanced Pressure Calibration
Your SMAN440 has the ability to perform a
linear adjustment of the pressure sensors based
on refrigerant type, temperature, and pressure.
Calibration setup: For best results, rst perform both the
Temperature and Pressure Zeroing procedures. See Calibration
section for details. This will ensure pressure readings are zeroed
and thermocouple is properly calibrated to the SLT port of the
SMAN. Calibration to LLT port is not necessary for this calibration.
The refrigerant cylinder should be stored in a stable ambient
environment for at least 24 hours before calibration.
1 Plug in a Type K thermocouple into SLT. (A bead type
thermocouple, like the ATB1, is recommended.)
2 Connect the SMAN440 to a refrigerant cylinder of a known,
single refrigerant using an EPA approved service hose. Be sure
to open both HIGH and LOW side valves on your manifold and
cap the unused ports. (If caps are not available you can connect
both ends of a refrigerant hose to the two unused caps. Note:
Some refrigerant will remain in the hoses which will need to be
recovered.)
3 Press the REFRIGERANT button to match the refrigerant of the
cylinder you are using.
4 Attach bead-type thermocouple to the side of the cylinder using
tape. It is recommended to attach in the middle of the cylinder.
Important: Let the temperature of the thermocouple stabilize to
the refrigerant temperature for 1 to 2 minutes or until stable.
5 Open the refrigerant cylinder. The pressure inside cylinder should
now be displayed on both HIGH and LOW side pressure sensors.
6 Press the CALTest Pressure button. If successful, "Good" will
display for 3 seconds. If failed, "Err" will display for same time.
Your SMAN checks with its built-in P-T charts to compare the
temperature of the refrigerant in the tank to the vapor saturation
temperature based on the refrigerant you selected. If the measured
pressures on your SMAN are within ±3psi of the P-T chart pressure
corresponding to the vapor saturation temperature, the SMAN will
adjust the pressure sensor linearity to match the P-T chart.
Possible causes of failed "Err" pressure calibration:
1. Refrigerant tank was not stored in stable ambient conditions for at
least 24 hours.
2. Thermocouple attached to refrigerant tank was not properly
calibrated to SLT port of SMAN.
3. Thermocouple was plugged into wrong port LLT instead of SLT.
4. Incorrect refrigerant was selected on the SMAN.
