Auto Power Off (Apo); Temperature Calibration - Fieldpiece SMAN SM480V Operator's Manual

Auto Power Off (APO)

To save battery life, your SMAN manifold
automatically powers off after a set time of no
button presses
MENU/AutoOff
1. Use ARROWS to scroll through times (default is 30 min).
2. Press ENTER to select and exit. If changes were made, choose
whether or not you want to save changes.
• Press MENU to exit at any time. If changes were made, choose
whether or not you want to save changes.
• APO is automatically disabled when data logging.

Temperature Calibration

Thermocouples ( T/C) are not calibrated
directly Instead, each T/C jack (ODDB, SLT, LLT)
must be calibrated to the particular T/C that
is plugged into it Though it's possible for a
calibration to hold for years, it's best practice to
calibrate regularly if only to verify accuracy
Calibration is quick and easy, requiring just a
known temperature to calibrate to Ice water is
probably the most accurate and readily available
known temperature (32 0°F, 0 0°C) in the field
MENU/CalTemp
1. Stabilize a large cup of ice water by stirring. Pure, distilled water
will be the most accurate.
2. Immerse the sensing end of the thermocouple in the ice water.
3. Use ARROWS to select the temperature you want to calibrate (SLT,
LLT, or ODDB).
4. Press ENTER to select.
5. Use ARROWS to adjust the temperature to match 32.0°F (0.0°C)
making sure the ice water is continually stirred. The calibration
range is limited to ±7°F (±3.8°C) in order to help prevent mistakes.
6. Press ENTER to save and return to the list of temperatures.
• Press MENU to exit at any time. If changes were made, choose
whether or not you want to save changes.
• If you have a wireless thermocouple (model JL3PC) assigned and
wireless is on, calibration is for the wireless thermocouple.
• Calibration of a wireless thermocouple (model JL3PC) does not
override a wired thermocouple calibration. You can switch between
wired and wireless without having to recalibrate.
