1. 250V. Surge Test
Press “
” button to power on, simultaneously, press the “Class ll” button until the
display shows insulation setting “250V”. You can also set the 250V test when the tester is
on ,by pressing and holding down the “Class ll” button until it shows “insulation”
Once you turn the instrument “off” the 250v setting, defaults back to 500v when you turn the
Instruments back on. Repeating the procedure will reset it at 250v, this allows you to test
surge protected equipment
2.Zero Clearing
Connect the zeroing plug, Long press “Class I” button for 3 seconds and then release it,
the meter will check whether the connection is correct. If it does, the meter will clear the
resistance values of connection cable and the one inside the meter. This allows you to use
longer earth leads

3. Flash Indication
3.1 Under Earth Continuity test, solid “√” shows if protective conductor resistance falls
within 0.01Ω~0.1Ω; “√” flashes for the resistance value between “0.10Ω~0.50Ω” and
“×” displays for the range between “0.51Ω~19.9Ω”.
3.2 With Earth Continuity, Insulation Resistance tests all completed, the
Meter would show “FAIL”if one of these items displays “×”If the meter displays
“PASS” and at the same time one
“√” flash, the word “PASS” will also flash
4. Testing a Class 1 Equipment
Plug the appliance into the mains socket (A).
Plug the earth test lead into the rear socket (F). Connect the
earth test crocodile clip/probe to an exposed earthed metal part on the appliance. If there is a switch on the
appliance, ensure it is in the “on” position. Press Class 1 button the earth test will be carried out, if the test
result is a SOLID PASS, this indicated the result is less than 0.1 of an ohm. However if the PASS is
FLASHING this indicates the result is between 0.1 to 0.5 of an ohm, this could be due to the length of the
lead connected to the appliance. If the appliance under test has only a short lead then this result must be
investigated. The Insulation Test will follow.
If the result is a FAIL on the earth, ensure that you are not connected to a piece of metal
which has
7
been painted or a metal screw that only into plastic and not connected to an earth.
In the case of an earth
path which has been painted try using the probe to penetrate the painted surface, then repeat the test. The
pass band on the SafetyPat is set up to include 0.5 of an ohm, a failure could be because you are testing an
appliance with a long lead, having a resistance greater than 0.5 of an ohm, this would be why the appliance/
extension lead has failed the earth test
Likewise if a reading was produced from testing an item with a very short lead, of 0.5 of an ohm, then this
should be investigated as the competent person doing the test must realise that the result would have been
less than 0.1 of an ohm ie a SOLID PASS
Having a FAIL on insulation with a class 1 appliance, where the pass band is set at 1Mohm usually indicates
the appliance has an insulation fault however depending on the appliance under test this sometimes can be
caused by a heating element in the appliance which is damp or dusty. Cleaning the appliance or connecting
it to the mains supply can soon burn off this damp or dust, then repeat the test

(See Diagram 3 connections)
NOTE having no earth would appear on the display as × Earth Cont ×FAIL flash
once you have found a good earthing point, re-test by pressing Class I button
NOTE If the measured value is of a low load it will be displayed as“
”This could mean that the appliance has
a low load or that the fuse has blown, however the most come fault is that the appliance under test has not
been switched on. Correct the fault and re-test
PASS or FAIL will be displayed as the final result

press ClassII button to repeat the test.
If the test is a Fail this will mean that the result is <2Mohm which means the insulation has broken down,
however if the appliance under test has an heating element it could mean there is moisture on the element or
10
dust, especially if it hasn’t been used for some time, try cleaning the item or connecting to power for a short
time to burn off any moisture, then re-test
The final result will be displayed as PASS or FAIL
6. Testing a mains cord (IEC) & Extension Lead
Plug the IEC Lead plug into the 13a socket on the tester, link the end of the IEC lead into the
connection at the rear of the tester.
For an Extension Lead, plug the mains plug of the extension lead, into the 13a socket of the tester, reel off
the cable from the extension lead. Then connect the IEC Lead that came with the , tester into the 13a outlet of
the extension lead .Complete the loop by connecting the other end of the IEC Lead into the appropriate socket
outlet at the Rear of the Tester
Press the Cord button to start the test, providing everything is ok the tester will carry out the
Earth, Insulation and Polarity tests with individual result and an overall PASS result
FAIL Indication displayed as ×EarthCont
sign flashes
Earth Test displays as“√”or“×”
Insulation Test displays as “√”or“×”
Polarity test,The unit will proceed with the wiring test, checking the live and neutral conductors for short or
11
open circuits or reversed connections and it displays as “√”or“×” and
displays
“PASS or FAIL” as the final result
NOTE
When testing Extension Leads it should be noted that this tester has a Pass Level of up to 0.5 of an ohm.
Indicated as a Pass or Fail, Some extension leads may have, because of their length more than 0.5 of an ohm
in resistance. This should be taken into consideration when testing Extension Leads.
7. Checking a mains power outlet
Connect the IEC power cord supplied with the tester into the unit socket (G) and plug the mains plug of the
power cord into the mains power outlet to be tested.

earth connection this will be indicated as follows
“LN√,LE×,NE×”
If there is a fault with the Neutral connection this will be indicated:
“LN×,LE √,NE×”
If the mains socket wiring is correct the display will be indicated:
“LN√,LE √,NE√
8. Maintenance
Battery Replacement
When the battery voltage is low the display indicates
you need to replace, all the batteries. Battery
replacement is as follows. We recommend the use of “Alkaline Batteries”
1) Disconnect all test leads from terminal inputs before battery replacement。
2) Power off the unit
3) Loosen the screw of the battery compartment and then remove the old batteries
4) Use 8 pieces of AA cell LR14 battery (Alkaline)
5) Correctly position the polarity "+" and "-" of each battery in the battery compartment
6) Then tighten the screw on the battery cover, turn on the unit and check that the Display comes on, if the
display does not come on re-check the polarity of the batteries, if this is ok roll your hand over the batteries, so
13
they rotate, this is to ensure a good contact, sometimes a protective film is applied to new batteries which can
prevent good contact when first fitted
We recommend that if the unit is not used for over 2 to 3 weeks that the batteries are removed from the unit.
Any contamination of the battery contacts or compartment should be cleaned with a dry cloth.
9. Cleaning
Clean only with a dry cloth; do not use solvents.
10. Calibration & Repairing
