 The KEW 6516 tester incorporates Anti Trip Technology (ATT) which electronically bypasses RCDs when performing loop impedance tests. This saves time and money by not having to take the RCD out of the circuit during testing and is a safer procedure to follow.
With the ATT function enabled, a test of 15mA or less is applied between line & earth. It enables loop impedance measurements without tripping RCDs rated at 30mA and above.
ATT supports measurements using three wires: Line, Earth, and Neutral and also two wires: Line and Earth.

Bluetooth communication
KEW 6516BT has a Bluetooth communication function and can exchange data with Android/ iOS tablet devices.
Before starting to use this function, download the special application “KEW Smart *” via the internet.
Large LCD & HELP function
- All the test data is shown in one large colored screen.
- HELP function will show how to connect the instrument according to the function selected
Operation in 3 simple steps & Hands free testing
- Set the rotary dial to your testing range.
- Connect the instrument to the installation under test.
- Press the test button.(By remote probe or using the Lockdown function of the test button.)
Anti-Trip Technology (with 2 & 3 wire)
For no trip LOOP L-PE testing on all RCDs.
With 3 wire (L, N, PE), to get the best accuracy readings.
With 2 wire only, very useful in case of no Neutral (i.e. 3-phase motor lines).
Loop Impedance 0.001 resolution
High test current range of 2Ω with 0.001Ω resolution.
Zs/Ra Limit
Zs Limit compares the values required by Electrical Installations Standard with measured results.
The verification of safety requirement on an electrical installation is simplified by using Zs/Ra Limit function. This function will automatically check if the measured loop impedance for TN (or earth loop for TT) is low enough to trip (disconnect) the MCB / Fuse / RCD giving the result of PASS or FAIL on the display.
SPD test
SPD (Surge Protection Device) which contains varistor can be tested measuring the tripping voltage without damage it.
PAT test
PAT test (PAT = Portable Appliance Tester) It is possible to check the insulation resistance and earth bond continuity of portable appliances for class I and II.
Connectivity
Use the PC application KEW Report to improve work efficiency.
KEW 6516 can download the test data by connecting the USB adaptor (Model 8212-USB) and then print complete Test Reports by a PC.
