4.1 Low-liquid sensor
When the dispensing liquid inside the syringe is low, the low-liquid sensor detects it and issues a warning.
The low-liquid sensor consists of a sensor head and an amp section. The sensor head is installed at the side
of the nozzle mounting section, while the amp section is installed on the top of the dispenser head assembly.
The low-liquid sensor must be readjusted after changing the type of liquid or after replacing the low-liquid
sensor itself.
c
CAUTION
Prepare a used (empty) syringe and a syringe full of liquid before starting adjustment. Accurate adjustment will not be
possible if only an empty syringe is used.
