2.5 Logging

Gasman incorporates both data and event logging which can be

accessed using the RS232 communications link available with the Single

Way Charger Interface (part No.C01940), using Crowcon Portables PC

software. See section VIII.

Data is recorded every minute (this rate can be adjusted using the PC

software). The log can record 900 hours of data at 1-minute intervals.

diagnostic events including:

• Switch on and switch off;

• Level 1, Level 2 and TWA, alarm on, alarm off and the peak level

during the alarm;

• Zero, calibration and gas test with success or failure;

• Flammable sensor saver on and off;

• The battery condition is logged every switch on and switch off

while the instrument is operating, and certain configuration

changes are also logged;

• The Event log can record over 4800 events.
