Configuració
Instal·lació de la bateria
The DY4100 requires 6 x AA 1.5V batteries (UM3) and 1 x 12V battery (not included). To install or replace batteries:
- Ensure the device is turned off (Function Switch set to "OFF").
- Localitzeu el compartiment de la bateria a la part posterior de la unitat.
- Obriu la tapa del compartiment de la bateria.
- Insert the batteries, observing correct polarity (+/-).
- Tanqueu bé la tapa del compartiment de la bateria.
A low battery warning symbol will appear on the display when batteries need replacement.
Connexió de cables de prova
Connect the test leads to the appropriate terminals (E, P, C, V) according to the specific earth resistance testing method being used (e.g., 3-pole or 2-pole method). Refer to standard electrical testing practices for correct lead placement for your application.
Instruccions de funcionament
Mesura de la resistència de la Terra
- Ensure the device is properly set up with batteries and test leads connected.
- Turn the Function Switch to the desired earth resistance range (20Ω, 200Ω, or 2000Ω). The device features auto-ranging within these selections.
- Premeu el botó Prova key to initiate the measurement. The green "OK" lamp hauria d’il·luminar.
- Read the earth resistance value displayed on the LCD.
- Per retenir la lectura, premeu la tecla Aguanta key. Press it again to release.
- After measurement, turn the Function Switch to "OFF".
Measuring Earth Voltage
- Connect the test leads for earth voltage measurement (typically between E and V terminals).
- Turn the Function Switch to the "EARTH VOLTAGE" position.
- El volum de la terratage will be displayed on the LCD. No "Test" button press is required for voltage mesura.
- After measurement, turn the Function Switch to "OFF".
Manteniment
- Neteja: Netegeu el dispositiu amb un drap suau i sec. No utilitzeu productes de neteja abrasius ni dissolvents.
- Emmagatzematge: Guardeu el provador en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes. Si l'emmagatzemeu durant períodes prolongats, traieu-ne les piles per evitar fuites.
- Calibració: Regular calibration by qualified personnel is recommended to ensure measurement accuracy.
Resolució de problemes
| Problema | Causa possible | Solució |
