b. Resetting Time Totalizing Meter. Connect lead from time totalizing meter electric reset device - 6645-179-2712 to connection on meter and plug reset device into a 110 volt electrical circuit. The time totalizing meter and the time totalizing meter reset device both have a four digit, accumulative time, recording system. To determine the number of hours required to reset the time totalizing meter to a zero reading, add the number of hours registered on the time totalizing meter to the number of hours required to equal 10,000. Example: a time totalizing meter registration of 0500 and a reset device setting of 9500 will advance the time totalizing meter until a reading of 0000 is achieved. Refer to figure 6-256 and follow the instructions to establish the correct procedure to calibrate the time totalizing meter electric reset device. 1. 2. 3. 4. 5. 6. Plug reset device into 110 volt electrical circuit being sure power switch (A) is in the off position. Depress reset knob (B) and lock by turning ¼ turn clockwise until tbe white line on knob is in a horizontal position. Open preset cover (C) and dial in the desired numbers, when added to the reading on the time totalizing meter equal a 10,000 hour meter reading. Close preset cover (C) and unlock reset knob (B) by turning ¼ turn counterclockwise. Turn power switch (A) on the depress start switch (C) to begin resetting. Unit will complete resetting and stop automatically. Should unit stop slightly short of zero, introduce ad- ditional counts by momentarily depressing start switch (D). Figure 6-256.
