MultiSafe TT 1 light rail system retractable voltage detector

The MultiSafe DSP TT1 is a safety device for fast voltage testing on overhead lines of light rail systems.
The Multisafe TT1 is a bipolar retractable voltage tester that can test voltages up to 1000V AC /1500V DC.
The device is particularly suitable for fast and safe detection of contact cable voltages in light rail systems.

Characteristics
• Accurate display of up to 1000 V AC/1500 V DC voltage
• Adjustable test height up to 6.2 m
• During the test, the protection resistor provides high safety, the maximum current is less than 3.2mA
• Simple operation with single button, self-test, protection resistance and proper grounding
• Replaceable magnetic contact or fixture inspection
• Additional load for detection of residual voltage and interference voltage
• Short models are available
• Length 1.3 meters, easy to transport
• Optional clamp, additional load for detection of residue and interference voltage

Repeat inspection and calibration
For voltage tester exceeding 1kV, repeat check
The inspection time limit does not exceed 6 years, which also applies to voltage testers up to 1000V.
Depending on the field of application and the needs of the measuring test instrument, repeated checks or repeated calibrations can be carried out within a shorter period of time.
Repair
We set high requirements for our measuring and testing instruments and always carry out quality control.
The most modern electronics and high-quality materials guarantee a long service life.
If the tester is damaged or malfunctions, we can repair it quickly.

Advantages
Robust design
Quality components guarantee functionality and safety:
• 4/6 section GRP retractable tube, height adjustable
• The display unit is made of impact-proof plastic material with a crash-proof display housing
• Dustproof and waterproof
Three sets of display system
• Red LED indicates voltage, green LED indicates standby and no voltage
• Voltage value, frequency and voltage type and polarity display
• sound signal when voltage exceeds Ut limit
Convenient operation
Fast detection can be achieved in three steps ︰
1. Place the magnetic contact head on the ground rail, or fix the contact clamp screw on the rail foot.
2. Run self-test
3. Pull out the telescopic part to the appropriate length and insert the electrode at the top.
Transport length/maximum test height
■ S = 1,31 / 6,20 m
■ M = 1,61 / 6,20 m
■ L = 1,61 / 8,20 m
■ XL = 2,10 / 10,0 m
Due to its heavy weight, XL code is recommended to be used above 8 meters.
