Caution
Before using your KTD30 please read these instructions; in particular note the safety
issues that follow:
Your tester is for use on dead circuits only. Although your Kewtech instrument is fully
protected against accidental connection to a live circuit it is essential to check the
circuit is dead before working on it.
Your tester is equipped with a very convenient auto test (hands free) feature but do not
touch the lead tips when using this feature.
There may be capacitance on the circuit being tested (a longer than normal test time
will indicate this condition). Your tester will automatically discharge this but do not
disconnect the test leads until this auto discharge has completed.
On the subject of test leads, always check for damaged leads or croc clips - Kewtech
replacement lead sets are inexpensive and easy to obtain.
The continuity circuit is fuse protected against accidental connection to mains (unlikely
as there will be a warning to indicate a live circuit) - if this fuse does blow replace it
with the correct type F 500mA fast blow ceramic 500V. It is located inside the battery
compartment.
BS EN 61010-1
Batteries
Because of storage issues your tester is not supplied with batteries.
ALWAYS REMOVE THE TEST LEADS BEFORE REPLACING BATTERIES.
Just 4 AA cells are required (alkaline recommended). The battery compartment is at the
the back of the instrument, remove the screw (do not lose it) – slide the battery cover
off and carefully insert the batteries observing correct polarity. Replace cover and fix
screw back in. 4 good quality AA alkaline cells should give 5000 tests at 500V DC.
Note: Access to the protective fuse is also gained through the battery compartment.
Always replace with the correct type – F 500mA Fast Blow Ceramic 500V.
