Using the L9788-10 Test Lead with Remote Switch (Red)

Replacing the Tip Pin (optional) for the L9788-10

When the tip pin of the L9788-10 Test Lead with Remote Switch 

(Red) (option) is worn out or broken, it can be replaced. The tip pin 

can be purchased via authorized Hioki distributor or reseller.

OFF

1 

Turn off the rotary switch and 
disconnect the L9788-10.

L9788-90 Tip Pin

Wrench 

 

(size: 7 mm width)

2 

Remove the tip pin by rotating 
with a wrench.

3 

Attach the new tip pin to the 
L9788-10 by rotating with a 
wrench.

(Tightening torque: 0.3 N·m)

4 

Check the operation.

Measure a measuring object of known 

values and use after checking that the 

resistance is correct.

Attaching the L9788-92 Breaker Pin

Remove the sleeve of the L9788-10 and attach the breaker pin.

Fully insert.
