Intelligent Pneumatic Circuit

Comes with self-check features: Sensor sensitivity, Air-valve performance

K(Ve) Auto Setup

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

Leak Limits

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

Electro-pneumatic Regulator

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

Noise Reduction (NR)

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

Operation Manual Download

Operation manual in each language can be downloaded through the USB port.

Drift Compensation

Mastering, Auto-Drift Compensation, Compensation Limits, Number of Samples

Self Check

Air-operated valve performance, DPS/PS Offset, CPU performance and others

Exhaust Interference Prevention

Exhaust timing will be controlled for the cases where multiple cavities are tested simultaneously
