Fast measurement · Inherently safe · High accuracy · Easy to use · Proven reliability · Compatiable with DT80
DESCRIPTION： The SupaRule CHM 300DT Cable Height Meter is a handheld meter for measurement of cable sag, cable height distance, and overhead clearance of conductors. It is a modern alternative to telescopic measuring poles. The CHM 300DT Meter utilises ultrasonic signals to determine the height of overhead cables up to 15m (50feet) Used by line operators within the utilities industries, e.g., electricity and telecommunications, the CHM300DT measures the height and separation of up to 3 wires. The CHM300DT has the additional feature of measuring horizontal distances up to 150 feet (45m), with the aid of the optional Dynamic Target(DT80).
APPLICATIONS： Applications include height measurement of:
Telephone lines
Distribution lines
Transmission lines
Cable television
Street lighting
SAG (lowest point to ground)
Pole Span
Distance measurement across busy roadways
Clearances on construction sites

Cable Height Meter It is a new version handheld cable height meter for measuring the cable sag, cable height and overhead clearances, it is a unique and modern alternative to telescopic measuring poles Special Features :
Quick Measurement: Measure 6 cables (with BTM/TOP switch on the front panel, measurement can be done from top down or bottom up). Have an increased ranged to 30m. Also can use this meter to measure the distance to the wall (in the room), to the poles, to the transformer, etc. up to 25m
Safety：Sonar principal to do the measurement, not need to touch the high voltage cables
High accuracy: use dipper cone, improve the accuracy and measure higher up to 30m. Improved design on anti-noise and sensitive on measurement.
Easy to use: Keep the three keys design, redesigned cone which will help on focusing the cables and reading in the same time. Easy to do calibration: CAL/MEA Mode switch allows the user to periodically check the meter by themselves.
Small size: Small in size and light weight, easy to carry
PC software: The Datalog function (Option) can store the site measurement in the datalog memory, and then down load to the PC, it allows the user to analysis the cable height trend by season, time and temperature
Datalog software It is a new version handheld cable height meter with datalog function (option), it keeps the measurement data in the datalog, then down load these data to the PC, using the datalog software to do the further analysis and generate the report
The datalog keeps the following data:
Location：character string, like “utility pole 210”
Date and time: Year, Month, Date, Hr, min.
Environment Temperature
Cable height measurement data
Note: the location can be key in through character string on the datalog, or key in on the PC. The clock of the datalog can also be set up on PC
