Warnings

⚠️ WARNING! An excessively high resistance was measured in the fuse pre-test. This indication means that the device under test has extremely low power consumption or it is: not connected; switched off; contains a fuse that has blown. Select PROCEED or CANCEL.
⚠️ WARNING! Voltage on mains test socket between LN - PE terminals is higher than approximately 20 V (AC or DC)! Disconnect the device under test (DUT) from the instrument immediately and determine why an external voltage was detected!
⚠️ WARNING! Current on test probe (S/EB1 - PE) is higher than approximately 10 mA (AC or DC)! Disconnect the test probe from the device under test (DUT) and determine why an external current was detected!
⚠️ WARNING! The Simple test memory has reached the limit of 50 sequences.
⚠️ WARNING! The internal memory is full!
⚠️ WARNING! The calibration period will expire in less than 1 month. The instrument counts down the days.
⚠️ WARNING! The calibration period has expired. Recalibrate the instrument!
⚠️ WARNING! A high insulation test voltage will be present on the output of the instrument!
⚠️ WARNING! A high insulation test voltage is present on the output of the instrument.

2 Quick-test guide

2.1 Instrument test modes

Instrument has three main operation modes:

2.2 Carrying out a Simple test

  1. Set function: In Main menu select SIMPLE TEST.
  2. Select the appropriate test sequence: e.g., CLASS I, CLASS II, IEC, CLASS I PC.
  3. Carry out the simple test sequence: Press TEST to start test sequence. Certain tests will pre-select limits but will allow the user to adjust (if required).
  4. View results: After the test sequence is finished, Autotest results are displayed on the screen and an overall PASS/FAIL indicator is shown.

2.3 Carrying out a Shortcut test sequence

  1. Set function: In Main menu select SHORTCUT MENU.
  2. Carry out Shortcut autotest sequence: Press TEST to start autotest. Certain tests will preselect limits but will allow the user to adjust (if required).
  3. Set appliance type and protective measures: Use the TAB and UP and DOWN arrows to set the appliance type, class etc. or select (scan) the appropriate code.

2.5 Measurements

2.5.1 Earth Continuity

The instrument measures the resistance of the protective earth conductor. The test is performed with a test current of 200 mA.

Steps:

  1. Set parameters and limits: Output (test current), Limit (maximum earth continuity resistance), Time (test time).
  2. Connect the appliance to the instrument.
  3. Carry out the test.
  4. View results.

2.5.2 Insulation resistance

The instrument measures the insulation resistance between conductive parts and accessible conductive parts (Class I) or between conductive parts and accessible conductive parts (Class II).

Steps:

  1. Set parameters and limits: Output (size of test voltage), Limit (minimum insulation resistance), Time (test time).
  2. Connect the appliance to the Instrument.
  3. Carry out the test.
  4. View results.

2.5.3 Insulation-P resistance

This test measures the insulation resistance to protective earth.

Steps:
