3) Clear the min/max memory by pressing both keys (min and max) simulta-
neously. The LCD will display “CLR” when the memory is cleared.
4) Allow the unit to log min. and max. for as long as required.
Warning:
You may want to disable the Battery Save feature before using
the Datalogging Mode to prevent the CL300A from turning off prematurely.
5) At any time press the min. or max. to display the value stored.
6) Turning off the CL300A or changing modes will clear the memory. Be
sure to record your data before turning off the unit.
9. Maintenance
A. Battery Selection
The CL300A operates on a standard 9V alkaline battery or an optional
rechargeable 9V Ni-Cd battery. For most applications the 9V alkaline bat-
tery will suffice; however, in heavy use applications the 9V Ni-Cd may be a
better choice. The 9V Ni-Cd battery supplied by Omega will offer approxi-
mately 7 hours of continuous use on a full charge (the alkaline battery will
yield about 25 hours). The optional 1001-9V charger supplied by Omega
will provide an overnight charge rate (10-12 hours) and will also power the
CL300A for bench use while maintaining a float charge on the Ni-Cd bat-
tery.
Warning :
Never connect the AC adapter/ charger with the 9V alkaline bat-
tery installed.
To order the 9V Ni-Cd battery or AC adapter/charger contact
OMEGA Engineering.
B. Input Protection
The CL300A incorporates a fuseless input protection and will tolerate most
misconnections up to 250 VAC or 250 VDC for up to 30 seconds duration.
Because of this protection no fuse is required.
C. Calibration
The CL300A is designed to hold its rated accuracy for a minimum of one (1)
year. This instrument is tested to and meets published specifications. After
final calibration our products are stored in a controlled stock room and con-
sidered bonded storage. Depending on environment and severity of use
factory calibration is recommended every one to three years after initial
installation. Contact Omega Engineering’s Customer Service Department
