Suction check
• Accumulated indication shows the
operating flow rate or residual amount
(of
N2 etc.) in a gas cylinder.
The decimal point indicators flash in power-saving mode.
 Selection of
indication unit
User can select between ANR and Nl/min for each fluid.
[ANR] Indicates the flow rate converted to a volume under standard conditions: 20°C, 1 atm
(atmosphere), 65%RH
[Nl/min] Indicates the flow rate converted to a volume under normal conditions: 0°C, 1 atm (atmosphere).
 External input Can be selected from accumulated value external reset, auto-shift and auto-shift zero.
 Indication
resolution
Minimum unit setting can be selected from 1 l/min, 0.1 l/min and 0.01 l/min. Depends on the model.
Refer to the specifications (P. 33) for details.

Selection of fluid
Air, Nitrogen (N2), Argon (Ar) or Carbon dioxide
(CO2) can be selected using the buttons.
Secret code setting function
The user must input a secret code to cancel the
keylock mode. This ensures that only authorised
persons can operate the switch.
Power-saving mode
Turning off the display can save power consumption.
Detection
camera
• Flow control of
N
2
gas to
prevent lead
frame oxidation.
• N2 blow
prevents
distortion of
camera image
due to air
turbulence.
Depending on the installation conditions, it is possible to
add or remove the flow adjustment valve, change
the
fitting type
and the
piping direction
as desired.
