1.       Connect up to a 12V DC supply

Unit is powered using the black and red mains leads.

2.       Connect up external triggering devices to the two inputs provided

Left connection on upper unit = upper start on lab timer

Right connection on upper unit = lower start on lab timer

NC left connection on base unit = upper stop on lab timer

NC right connection on base unit = lower stop on lab timer

3.       Switch on the unit  and press “reset ”

4.       You are now ready to carry out the experiment

This unit does not offer accumulative timing and will need to  “reset ” after each experiment. The range is selectable while under test , so if the time counts above selected range depress “RANGE” to move the decimal place to the next higher range.

N.B.    The 4 mm banana socket is an alternative input power supply.
