• Display cable status and troubleshoot wiring for continuity, shorts,
opens and crossover.
Non Contact Voltage detection
• Tests voltage from 90 ~ 1000V, special design to make sure the
power is off before testing for circuit protection.
Polarity indication
• Identify the telephone line polarity easily.
Energy saving
• Automatically powers off after 1 hour of no operation.
ADVANCED FEATURES
• MT-7028 Transmitter generates: 1KHz audio signal with
two-tone (high / low) for selection. The maximum distance of
transmitter is ≧ 3 kilometers. Works with MT-7028 receiver
by volume adjustment feature can precisely find the break
point in the range of 10~30cm. The MT-7028 receiver
contains indicated LEDs which is more accurate for testing.
• MT-7028 Transmitter works with the receiver for cable
mapping by LED lights indication. The instrument can verify
cable status for continuity, shorts, opens and crossover on
RJ45 Lan cable and RJ11 telephone cable and test
shielding/ unshielded wire. The maximum length that can be
tested is 300 meters.
• MT-7028 Transmitter: LED indicators to detect the common
wire resistance (> 300Ω) for bad connection.

Telecommunications equipment and routers can be tested in
live Electrical environments without turning off the power.
The transmitter can also identify the positive and negative
polarity telephone lines.
• MT-7028 Transmitter：with low battery indication function
and will turn off automatically after one hour non-working.
• MT-7028 Receiver：with Non Contact Voltage detection
feature which can detect AC voltage from 90~1000V to avoid
danger and damage by detecting the voltage in advance.
• MT-7028 Receiver：with LED lighting and earphone jack to
allow the product to be used in noisy or dark environments.
