For EHV Microamp Measurement on Barehand Equipment
The Chance Ladder Monitor Kit is used with EHV Barehand maintenance to detect microamp leakage on a ladder before it is placed into use. This is accomplished by connecting the meter to the ladder, and taking readings as the ladder is placed in contact with the conductor.
It is recommended that readings be taken periodically during work progress to assure proper or optimum working conditions which could be altered by a change in the atmosphere.
The kit consists of a 200 micro-amp scale microammeter, three clamps to effect use on a three-rail ladder, a cable with clips and adapter to establish contact, a bracket to ground and hold the meter on the structure and two dry cell batteries. Instruction drawings for field assembly and operating instructions are included in the kit.
