Impact limits 20 joules (housing)
Calibration and setup Digitally controlled ZERO and SPAN pushbutton
setting
Signal fix The analogue output signal of the sensor is fixed
during calibration to prevent false alarms from
being initiated
Fault indication Under range signal transmitted and fault display
for:
• Loss of communications from the sensing
module
• Sensing module absent for more than 10
seconds
• Sensor over-range protect
Key coding Coding stops prevent insertion of a non-valid
sensing module.

Alarms Programmable GENERAL alarms and HIGH
alarms with an LED indicator.
The two adjustable alarm setpoints are preset
during manufacture to default values appropriate
to the type of sensor, determined by the sensing
module being used.
STEL andTWA Automatic calibration of STEL and TWA limits to
EH40 standards.
STEL: Exposure over 15-minute successive
periods
TWA: Exposure over a continuous rolling 8-hour
period
