Tetra Logging

Peak test

When performing a peak test, such as a vertical entry check, previous

readings can be cleared on entry to the peak display option.

Zero

The Tetra instrument can perform an autozero by selecting the Zero

function from the menu. When zero is completed, the instrument will

return to normal operation.

2.5 Logging

Tetra incorporates data and event logging which can be accessed using the IR

communications link with Portables PC software (See section VIII). It can record

data each minute for 50 hours up to a limit of 1500 events.

Tetra records the time and date for a number of operating and diagnostic

events including:

• Switch on and switch off

• Level 1, Level 2 and Time Weighted Average Alarms, alarm on,

alarm off and the peak level during the alarm

• Zero, calibration and gas test with success or failure

• Pellistor saver on and off

• The battery condition is logged every 15 minutes while the

instrument is operating, and certain configuration changes are

also logged.
