K(Ve) Auto Setup

K(Ve) can be setup using a calibrator, Leak Master or
Auto-Leak Calibrator (ALC) to convert measuredpressure to a flow rate.

Leak Limits

Two sets of leak limits: Large/Small leaks on
Work-side (UL/UL2) and Master-side (LL/LL2)

For the models come with Electro-pneumaticElectro-pneumatic
regulator, different test pressure can be setRegulator
independently for each channel.

External Exhaust Valve
Ready

Valve is sold separately.

Sensor Protection

ExhaustInterference
Prevention

Exhaust timing will be controlled for the cases wheremultiple cavities are tested simultaneously.

Charge Hold

Tester pressurizes the tested part continuously.
Used to locate leaks.

Control I/O Port

Both for NPN-PNP
For Phoenix Contact connector, wire connection canbe done with a flat-bladed screwdriver.

SerialCommunication

RS-232C: 2 ports (On the front and rear panels)
USB: 1 port

Noise Reduction(NR)

Eliminates noise by repeating the DET stage when
the reading falls between DET UL and DET UL2.
