rant (see fig. 5).
** LEVEL is display option.
If the display is set to “LEVEL” then the value
displayed will be:
PROBE LENGTH (entered in QUICK SETUP)
– DISTANCE (see fig. 5).
*** OUTPUT (%) is display option.
Will represent the level of refrigerant,in
percent, scaled (entered in QUICK SETUP)
according to: SCALE 4 mA (0%), SCALE
20 mA (100%) (see fig. 5).
**** OUTPUT I (mA) is display option.
Will represent the level of refrigerant,in 4-20
milliampere, scaled (entered in QUICK
SETUP) according to: SCALE 4 mA (4 mA),
SCALE 20 mA (20 mA) (see fig. 5).
