Fluke T6-600

Fluke T6-600 Electrical Tester w/ FieldSense contactless voltage measurement

Probes dock in the back for storage and when measuring current or contactless voltage.

Leads are thick and sturdy and not removable, but the probes are modular.

Back side with touch grounding point.

One self-tapping screw holds the battery cover.

Connection from touch ground point to black probe dock.  From here to the contact point measures &gt;500Meg and about 2.2nF at low frequency.

The dimples are from me probing this contact point.

Two more self-tapping screws and the unit is open.

Shielding around the fork end is connected back to the PCB via an elastomeric connector button.

Leads are connected with regular Faston connectors.

Leads are replaceable it seems.

A look at the PCB in situ.

A flexible ribbon connects the fork sensors to the PCB.

Other end of PCB.

One self-tapping and two machine screws fasten the PCB down.  The machine screws also connect the test leads to the board.

PCB removed.

Another look at the fork current and voltage sensing apparatus.

The top (display) side of the PCB.

The large component is a thin-film resistor array for the voltage divider and ohms voltage sense.

The connector for the fork sensors goes straight into a shielded section of circuitry.

A closer look at the top side showing the mini-speaker and input protection components.

Part of the input protection is a PTC thermistor.

The positive input area is isolated via routed slots. The negative input is coupled to system ground via inductor L6.

There does appear to be some components under the display.

Gas-discharge tube for over-voltage protection. Large fusible resistor dissipates power when the GDT fires.

Re-assembly successful.
