PrimeTest 100 Operating Instructions

2 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 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 or ③ will cause the tests to be performed with the insulation voltage as set in the Setup Menu. A long press on keys, ② or ③ will cause

PrimeTest 100 Operating Instructions

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 ①and the IEC socket on the end panel ⑦ and a Class 1 ②or Class II ③ appliance test is selected, the PrimeTest 100 will flash the Cord test ④ enunciator to indicate that the Cord test is the most appropriate test.
