b. Resetting Time Totalizing Meter.

Connec t

lead from time totalizing meter electric rese t

device - 6645-179-2712 to connection on mete r

and plug reset device into a 110 volt electrica l

circuit. The time totalizing meter and the time

totalizing meter reset device both have a fou r

digit, accumulative time, recording system. T o

determine the number of hours required to rese t

the time totalizing meter to a zero reading, add

the number of hours registered on the tim e

totalizing meter to the number of hours required

to equal 10,000. Example :

a time totalizin g

meter registration of 0500 and a reset devic e

setting of 9500 will advance the time totalizing

meter until a reading of 0000 is achieved. Refe r

to figure 6-256 and follow the instructions t o
