Page 5: Meaning Of Symbols And Markings
1.1 Meaning of Symbols and Markings Caution - risk of danger and refer to instructions Caution - risk of electric shock Equipment protected by double or reinforced insulation (Class II) (Measurement Category II) is applicable to test CAT II and measuring equipment connected directly to utilization points (socket outlets and similar points) of the low-voltage MAINS installation. - Page 6 The EZ165 & EZ365 must only be used on CAT II installations up to 300V to earth. Always verify the unit is functioning correctly on a known correctly- wired live socket before and after use.

Page 7: Description
If the wiring is faulty or the mains voltage is not within limits the earth loop impedance test is not performed. The EZ165 & EZ365 also indicate if the mains voltage is below 195V or above 270V or if the neutral to earth voltage is greater than 30V. -
Page 8: Operation
3. OPERATION 3.1. Description of Indicators The EZ165 & EZ365 use two rows of LED’s to indicate wiring condition, mains voltage level and earth loop impedance. The top row of three tricolour LED’s marked LOOP TEST indicates the range within which the measured earth loop impedance falls. -
Page 9: Using The Ez165 & Ez365
If the wiring test detected a fault, then the loop impedance test is not performed. If the EZ165 / EZ365 does not power up and none of the LED’s illuminate this could mean that the wiring is incorrect, or the mains voltage is less than 135V and investigation of the wiring is required. -
Page 10: Wiring And Voltage Check
3.3.1 Wiring and Voltage Check The condition of the wiring at the socket under test or any out of tolerance supply voltage will be indicated by the LED sequences of figure 1 on the lower row of LED’s. If a wiring fault is detected or the supply voltage is out of tolerance the top loop indicator LED’s will not illuminate as a loop impedance measurement is not made. - Page 11 Figure 2 .

Page 12: Loop Test
3.3.2. Loop Test If the wiring is correct and the supply voltage of the circuit under test is between 195V and 270V the lower indicators will all indicate green and one of the top indicators marked LOOP TEST will indicate the range into which the measured earth loop impedance falls. -
Page 13: Polarity Check
(i.e., Supply Line is connected to Neutral & Earth, Supply neutral & earth are connected to Line) then as with all standard socket testers EZ165 will not detect this fault. The EZ365 can detect this fault using the additional supply cross polarity check. -
Page 14: Rcds In The Circuit Under Test
This earth leakage current can approach the trip threshold of an RCD or RCBO, and the EZ165 / EZ365 test current will add to it with the possibility of the protective device tripping. -
Page 15: Maintenance Cleaning
The effect of highly inductive or capacitive loads and mains disturbances can be to reduce accuracy on the lower two ranges, e.g. if the actual loop impedance of the circuit under test is <1.7Ω then the EZ165 / EZ365 may indicate in the range 1.7Ω to 5Ω. 4.
