OPERATING INSTRUCTIONS
2.1
Initial Operation
The T477W Bonding Meter is shipped with charged batteries. If the meter is not used for a period of 30 days following
shipment, the batteries should be charged before use.
2.2
Battery Charging
Batteries are recharged by disconnecting the probe from the input connector J1 and connecting the battery charger B15693 to
connector J1. Batteries should nominally be charged for 14-16 hours. Continuous charging for prolonged periods (weeks or
months) is not recommended. Refer to Section VI for further details on battery charging and power sources other than 120
VAC, 60 Hz.
W A R N I N G
Do not attempt to charge batteries in hazardous locations. Battery charging should
be done only in a location known to be free from flammable gases or vapors.
2.3
Probes
One set of probes, Part Number C22161, is supplied with the T477W Bonding Meter. There are four optional probe sets
available that may be purchased separately. All of the probe sets are useful for particular applications; however, care must be
exercised in the use and selection of probes. The use of a particular probe set depends on the size and shape of the two bonded
materials in the vicinity of the bond. Below is a brief description of each:
