Martel Electronics TC100 - Manual (Page 13)

9. Maintenance
A. Battery Selection
The TC100 operates on a standard 9V alkaline
battery or an optional rechargeable 9V Ni-Cd
battery. For most applications the 9V alkaline
battery will suffice; however, in heavy use appli-
cations the 9V Ni-Cd may be a better choice.
The 9V Ni-Cd battery supplied by Martel will
offer approximately 7 hours of continuous use
on a full charge (the alkaline battery will yield
about 25 hours). The optional 1001-9V charger
supplied by Martel will provide an overnight
charge rate (10-12 hours) and will also power
the TC100 for bench use while maintaining a
float charge on the Ni-Cd battery.
Warning: Never connect the AC adapter/
charger with the 9V alkaline battery installed.
To order the 9V Ni-Cd battery or AC
adapter/charger contact Martel Electronics at
800-821-0023.
B. Input Protection
The TC100 incorporates a fuseless input pro-
tection and will tolerate most misconnections
up to 250 VAC or 250 VDC for up to 30 sec-
onds duration. Because of this protection no
fuse is required.
C. Calibration
The TC100 is designed to hold its rated accura-
cy for a minimum of one (1) year. It is therefore
recommend that an annual re-calibration be
done to ensure operation within specification.
