Introduction

The PrimeTest 100 is a hand held battery powered unit suitable for carrying out electrical safety checks on:

  • • Class I appliances
    • Class II appliances
    • IEC mains leads
    • Extension leads
    • Mains outlet wiring

Numbers shown in circles e.g. refer to figure 1  and figure 2 on page 6.

Test connections on the PrimeTest 100 are:

  • Mains socket on front panel for connecting the appliance under test.
  • 4mm socket on end panel for earth test probe
  • IEC socket on end panel for mains cord testing.

User Interface
The LCD display shows test progress, results for individual tests and the overall test result for an appliance or mains cord.
Tests are initiated using the three push buttons:
Power ON/OFF = 2+3 until two beeps are heard
Class I appliance test =2
Class II appliance test =3
Cord / extension lead test =4

Note:

  • A short press on keys 2,3,4or will cause the tests to be performed with the insulation voltage as set in the Setup Menu.
    A long press on keys 2,3 or 4 will cause the tests to be performed with the alternate insulation voltage from the Setup Menu. Eg 500V in Setup menu will result in a 250V insulation test.

  • By Accessing the settings screen by holding keys 3 and 4 you will also be able to enter the Setup Menu and change the pass/fail limit on the earth continuity test between 0.1/0.2/0.3, change the insulation voltage between 500 and 250V and choose between British Standard
    (3.5mA and 0.5mA) or IET Code Of Practice
    (5mA and 5mA) Protective Conductor and Touch Current leakage limits.
    Key 2 (Class1) to change Earth Continuity Limits
    Key 3 (Class 2) to change Insulation Resistance Voltage
    Key 4 (Cord) to change between leakage limits by standard.

  • The PrimeTest 100 will automatically switch OFF after approximately 3 minutes if no keys are pressed. The auto switch-off is disabled during a power socket test.

  • When a key is pressed to initiate a test sequence, the PrimeTest 100 will compare the type of appliance connected with the test sequence that has been selected, and where possible, will prompt the user if an inappropriate test has been selected.
    For example, if an IEC lead is connected between the front panel mains socket and the IEC socket on the end panel and a Class 1 or Class II appliance test is selected, the PrimeTest 100 will flash the Cord test enunciator to indicate that the Cord test is the most appropriate test.

Performing Tests

Press keys 2+3 to switch on the PrimeTest 100. When the unit is ready the display will be as shown below.

Checking a mains power outlet
Connect the IEC power cord to the PrimeTest 100 socket 7 and plug into the mains power outlet to be tested.
If the mains socket wiring is correct the display will show.

If the Live and Neutral in the socket wiring are reversed or there is a fault with the protective earth connection this is indicated by the display below.

If there is a fault with the Neutral connection this is indicated by the display below.

In the event of a test failure, disconnect the PrimeTest 100 from the supply and rectify the fault.
Do not leave the PrimeTest 100  permanently connected to a mains supply.
The auto switch-off function is disabled when the PrimeTest 100 is connected to a live mains socket. The unit will beep continually after 3 minutes to remind the user to disconnect from the mains socket.

Testing a Class I Appliance

  1. Visually inspect the appliance and mains cord for signs of damage.

  2. If the appliance passes a visual inspection proceed with the electrical tests.

  3. Plug the earth test lead into the 4mm socket 6 on the PrimeTest 100 end panel.

  4. Plug the appliance into the PrimeTest 100 front panel mains socket 1

  5. Connect the earth test probe to an exposed metal part on the appliance.

  6. If the Appliance under test has an ON/OFF switch, make sure it is in the ON position.

  7. Press the Class I test key 2

  8. The PrimeTest 100 will now test the continuity of the protective earth.

  9. If you are testing a Class I item with no exposed earthed parts an option to accept the high continuity measurement is given. When the continuity test fails you can long press key 2
    and the continuity and show as NC (not checked) on the result screen.

  10. If the continuity measurement is greater than the set limit but <0.5ohms then the PrimeTest 100 will ask whether a long lead is attached. Press the key to record the result as a pass or the key to record a fail.

  • If the measured value is less than the pre-set pass/fail threshold, the measured value is displayed and the unit indicates a pass result, as shown below.

Refer to section 2 for changing the pass/fail limits

  • The unit will proceed with the Insulation and Leakage tests.

Note: The power switch on the appliance under must be in the ON position to perform an insulation test. If no appliance is detected the PrimeTest 100 will display the following.

  • Check that the appliance power switch is in the ON position. The test will automatically proceed if the appliance power switch is placed in the ON position.
  • If the LO LOAd enunciator remains on the display, the load presented by the appliance may be too small for the PrimeTest 100 to detect. In this case, press the test key to continue.
  • During the Insulation Test the PrimeTest 100 will display the selected test voltage.
  • Refer to section 2 for changing the insulation resistance test voltage.
  • If the Insulation Resistance is greater than the factory set limit a tick is placed next to the Riso enunciator. If the Leakage current is less than the set limit a tick is placed next to the ILEAK enunciator.
  • The PASS enunciator is illuminated.

Testing a Class II Appliance

  • Visually inspect the appliance and mains cord for signs of damage.
  • If the appliance passes a visual inspection proceed with the electrical tests.
  • Plug the earth test lead into the 4mm socket  6 on the PrimeTest 100 end panel.
  • Plug the appliance into the PrimeTest 100 front panel mains socket 1
  • Connect the earth test probe to an exposed metal part on the appliance.
  • If the Appliance under test has an ON/OFF switch, make sure it is in the ON position.
  • Press the Class II test key 3
  • The PrimeTest 100 will now test Insulation Resistance and Leakage current.

Note: The power switch on the appliance under must be in the ON position to perform an insulation test. If no appliance is detected the PrimeTest 100 will display the following.

  • Check that the appliance power switch is in the ON position. The test will automatically proceed if the appliance power switch is placed in the ON position.

  • If the LO LOAd enunciator remains on the display, the load presented by the appliance may be too small for the PrimeTest 100 to detect. In this case, press the test key 3  to continue.

  • During the Insulation Test the PrimeTest 100 will display the selected test voltage.

  • If the Insulation Resistance is greater than the pre-set limit a tick is placed next to the Riso enunciator. Similarly, if the Leakage current is less than the pre-set limit a tick is placed next to the ILEAK enunciator.

  • The PASS enunciator is illuminated.

  • Should an earth path be picked up at the start of the test a message will appear asking to confirm that the EUT is Class II FE if it is and you wish to continue the test then press key 3 and the test will start. The value for the continuity will be shown but no pass/fail marker against it. It will then carry on with the following tests but automatically drop the test voltage to 250V for the insulation resistance.
    Refer to section 2 for changing the pass/fail limits.

Testing a mains cord

  • Visually inspect the mains cord and plug for signs of damage.
  • Check that the correct fuse is fitted.
  • If the cord passes a visual inspection proceed with the electrical tests.
  • Plug the mains cord under test into the IEC socket 7  and the front panel mains socket 1 on the PrimeTest 100.
  • Press the cords test key 4
  • The PrimeTest 100 will first test the continuity of the protective earth.
  • If the measured value is greater than the pre-set limit a cross is placed next to the RPE enunciator, a FAIL is indicated.

Note: The protective earth resistance will depend upon the length of the extension lead and the size (cross sectional area) of the cable. The measured value may be acceptable even if a cross is shown next to the RPE enunciator. For reference, typical resistance values for a variety of cable lengths and cross-sectional area are given in Table 1.

  • If the continuity measurement is greater than the set limit but <0.5ohms then the PrimeTest 100 will ask whether a long lead is attached. Press the key 4 to accept the result as a pass or the key 3 to record a fail.
  • The unit will proceed with the Insulation test.
  • If the Insulation Resistance is lower than the pre-set limit a cross is placed next to the Riso enunciator and the test sequence is halted.
  • If the Insulation Resistance is greater than the pre-set limit a tick is placed next to the Riso enunciator.
  • The unit will proceed with the wiring test, checking the live and neutral conductors for short or open circuits or reversed connections.
  • If the wiring is correct a tick is placed next to the cord enunciator, the GOOd enunciator is illuminated and a PASS is indicated for the sequence.

Refer to section 2 for changing pass/fail limits.
Note: If the tested cord has a wiring fault, one of the following enunciators will be illuminated in place of GOOd

  • OPEn indicates that either the live or neutral conductor is broken (open circuit) or the plug top fuse has blown
  • Short indicates that the live and neutral conductors are shorted together
  • CrOSS indicates that the live and neutral connections are crossed (live and neutral conductors reversed)

Testing an extension lead

  • Visually inspect the mains cord and plug for signs of damage.
  • Check that the correct fuse is fitted.
  • If the cord passes a visual inspection proceed with the electrical tests.
  • Plug the supplied 0.5m red IEC lead into the IEC socket and into a mains outlet on the extension lead. Plug the mains plug of the extension lead into the front panel mains socket 1  on the PrimeTest 100.
  • The extension lead can now be tested in the same manner as an IEC as described above.

Note:

  • The protective earth resistance will depend upon the length of the extension lead and the size (cross sectional area) of the cable. The measured value maybe be acceptable even if a cross is shown next to the RPE enunciator.
  • If the continuity measurement is greater than the set limit but <0.5ohms then the PrimeTest 100 will ask whether a long lead is attached.
    Press the key 4 to accept the result as a  pass or the key 3 to record a fail.
