Specifications (continued)
Length
Accuracy
±2 feet for cables less than 10 feet
±5 feet for cables longer than 10 feet
and shor
ter tha
n 200 feet
±3 % and ±5 feet for cables longer than
200 feet
High
Voltage
Detection
An ac
voltage of more than
5 V rms will trigger the High Voltage
Wa
rning.
Measurement
Rate
Maximum of 4 complete measurements
per second, decreasi
ng to 2 seconds per
measurement based on cable size and
uniformity.
VOP Adjustable from -20- to -99-, retained
during power off. Default to -66-
when
batteries are changed.
Measurement
Te
chnology
Time Domain Reflectometry (TDR) with
50 drive impedance, 6 V maximum
pulse height.
Low
Battery Indicator flashes when battery voltage
falls
below 4.1 V
Tone Injection Approximately 1 kHz at an amplitude of
80 % of bat
tery voltage. Variable
frequency and cadence. Tone
characteristic is changed as cable
condition changes to “normal-open”
from any other condition.
Cable Type Virtually all two or more conductor
cables
