UNIVERSAL CHARGER

The 70 series detector comes equipped with a universal charger that can be used with electrical systems that are 100 – 0 volts and 50/60 Hz. The universal charger
comes with  optional plugs to fit most electrical outlets found throughout the world. To assemble the charger, select the plug for the system you are using and attach it to
the charger. To attach the plug to the charger, slide it onto the charger until it clicks into place. Ensure it is securely attached to the charger before using it. To change plugs
on the charger, depress retaining clip and slide the plug up and off the charger.

DATA LOGGING

The 70 series detector is equipped with data logging capability. The data logging can be enabled or disabled at the start of each session during warm-up (see Viewing
and Changing Settings section). The data log rate is one set of readings per minute with sufficient capacity to hold more than 6 months of records (assuming 0 hours of
operation per week). The data logging rate automatically changes to one set of readings every 5 seconds when the unit is in alarm.
Each data logging session includes information contained in the session header including user ID, date and time that session started, sensor types, serial number, alarm
levels, last test date, test gas concentration and explosive gas type. A session begins when the unit is turned on and ends when the unit is turned off. Each reading will
record average gas readings for the interval for each sensor, STEL and TWA readings for CO and H
When the data log memory is full, a "DATALOG FULL" message will be displayed during the start up sequence. Pressing the POWER/SELECT button will clear this message.
Once the data log memory is full, the data from the oldest session will automatically be deleted to ensure that there is enough room for the current session.
You can download the data to a Windows 98 (Second Edition), Windows 000 or a Windows XP equipped computer.
