5. Opstelling

5.1 Battery installasie

The DY4100A/B requires 6 x AA (No. 5) batteries (not included). To install:

1. Vind die batteryklepdeksel aan die agterkant van die instrument.
2. Gebruik 'n skroewedraaier om die deksel oop te maak.
3. Plaas 6 AA-batterye in en verseker die korrekte polariteit (+/-).
4. Plaas die deksel van die batterykompartement terug en maak dit met die skroef vas.

5.2 Connecting Test Leads and Earth Spikes

For accurate earth resistance measurements, proper connection of test leads and auxiliary earth spikes is crucial. Refer to the specific measurement method in the operating instructions for detailed connection diagrams.

6. Bedryfsinstruksies

6.1 Algemene meetstappe

1. Ensure the instrument is clean and in good working condition.
2. Installeer nuwe batterye.
3. Kies die verlangde meetfunksie met behulp van die draaiknop.
4. Connect the test leads and auxiliary earth spikes according to the specific measurement method.
5. Druk die TOETS knoppie om die meting te begin.
6. Lees die meetwaarde op die LCD-skerm.
7. After measurement, turn the rotary dial to the OFF position.

6.2 Earth Resistance Measurement (2-pole or 3-pole method)

The DY4100A/B supports 2-pole and 3-pole earth resistance measurements. For 3-pole measurement, connect the test leads as follows:

• Connect the green lead to the 'E/COM' terminal and to the earth electrode under test.
• Connect the yellow lead to the 'S' terminal and to the potential auxiliary earth spike (P1).
• Connect the red lead to the 'ES' terminal and to the current auxiliary earth spike (C1).
• Ensure the auxiliary earth spikes are driven into the ground at appropriate distances from the earth electrode under test (typically 5-10 meters apart).
• Select the appropriate resistance range (e.g., 20Ω, 200Ω, 2000Ω) using the function dial.
• Druk die TOETS button. The measured earth resistance will be displayed.

6.3 Soil Resistivity Measurement (DY4100B only)

The DY4100B model is capable of measuring soil resistivity (ρ). This typically involves the Wenner method using four earth spikes.

• Connect the four test leads to the 'V', 'S', 'ES', and 'E/COM' terminals and to four equally spaced earth spikes (A, B, C, D) driven into the ground.
• Ensure the spacing 'a' between the spikes is consistent.
• Select the soil resistivity function on the dial.
• Input the spike spacing 'a' if required by the instrument (refer to specific DY4100B manual for input method).
• Druk die TOETS button. The soil resistivity (ρ) will be calculated and displayed.

6.4 Vlugtage Meting

The instrument can measure AC voltage to ground and photovoltaic DC voltage.

• AC Voltage na grond: Connect the test leads to the 'V' and 'E/COM' terminals. Select the AC voltage function. The voltage sal vertoon word.
• Fotovoltaïese Voltage: Connect the test leads to the 'V' and 'E/COM' terminals. Select the DC voltage function. The photovoltaic open circuit voltage will be displayed. The DY4100A/B offers a wide range up to 1500V for photovoltaic measurements.

• Onakkurate lesings:
  • Maak seker dat die toetsdrade stewig gekoppel en nie beskadig is nie.
  • Verify auxiliary earth spikes are properly driven into the ground and at correct distances.
  • Check for strong electrical interference in the testing area.
  • Ensure the correct measurement range is selected.
• "OL" of Oorlading Aanduiding: The measured value exceeds the selected range. Switch to a higher range or check for open circuits.
• Lae battery aanwyser: Vervang alle batterye deur nuwe batterye.
