LARIAU TS58 Digital Insulation Resistance Tester

1. Introducció

The LARIAU TS58 is a digital insulation resistance tester designed for measuring insulation resistance in various electrical equipment and insulating materials. This includes transformers, motors, cables, switches, and other electrical appliances. It is suitable for maintenance, repair, and testing applications.

This instrument features automatic voltage release, high stability, and reliability. It offers a maximum display count of 2000, 100 groups of data storage, and an insulation resistance measurement range of 0.1 MΩ to 10 GΩ. It also includes AC/DC voltage measurement capabilities and advanced DAR (Dielectric Absorption Ratio) and PI (Polarization Index) measurements for more accurate insulation assessment.

4. Configuració

4.1 Instal·lació de la bateria

The TS58 is powered by 8 x 1.5V AA/LR6 batteries (not supplied). To install or replace batteries:

1. Localitzeu el compartiment de la bateria a la part posterior de l'instrument.
2. Obriu la tapa del compartiment de la bateria.
3. Insert 8 AA/LR6 batteries, ensuring correct polarity (+/-).
4. Tanqueu bé la tapa del compartiment de la bateria.

A low battery indication will appear on the display when batteries need replacement.

5. Instruccions de funcionament

The TS58 is designed for measuring insulation resistance and AC/DC voltage. Always ensure the test leads are securely connected to the instrument and the circuit under test.

5.1 Mesura de la resistència d'aïllament

1. Connect the test leads to the appropriate terminals on the TS58 and to the equipment under test.
2. Enceneu l’instrument.
3. Use the 'SELECT' button to choose the insulation resistance measurement mode.
4. Ajusteu el volum de sortidatage (50V/100V/250V/500V/1000V) using the up/down buttons as required for your test.
5. Press the 'TEST' button to initiate the measurement. The high voltagL'indicador s'il·luminarà.
6. Read the insulation resistance value on the LCD screen.
7. After the test, the instrument automatically discharges the circuit.

5.2 AC/DC Voltage Mesura

1. Connect the test leads to the appropriate terminals on the TS58 and to the voltage font.
2. Enceneu l’instrument.
3. Use the 'SELECT' button to choose the AC or DC voltage mode de mesura.
4. Llegeix el voltage value on the LCD screen. The measurement range is 10V-600V.

5.3 DAR and PI Index Measurement

The DAR (Dielectric Absorption Ratio) and PI (Polarization Index) measurements help assess the quality and aging status of insulation, mitigating the effects of temperature, humidity, and interference currents.

1. Perform an insulation resistance test as described in section 5.1.
2. Press the 'PI/DAR' button. The instrument will automatically compute and display the DAR and PI values.
3. Refer to industry standards for interpreting DAR and PI values to evaluate insulation condition.

5.4 Emmagatzematge i recuperació de dades

The TS58 can store up to 100 groups of measurement data.

• To save data: After a measurement, press the 'HOLD*' button to hold the current reading, then press 'MEM READ' to save it. (Note: The exact sequence might vary; refer to the full manual for precise steps if available).
• To recall data: Press the 'MEM READ' button and use the up/down arrows to navigate through stored data groups.

6. Manteniment

6.1 Neteja

Wipe the instrument's exterior with a soft, damp drap. No utilitzeu productes de neteja abrasius ni dissolvents. Assegureu-vos que no entri humitat al dispositiu.

6.2 Emmagatzematge

When not in use for extended periods, remove the batteries to prevent leakage. Store the instrument in its zipper carry bag in a dry environment, away from direct sunlight and extreme temperatures. The recommended storage environment is -10~50℃, <75%RH.

7. Solució De Problemes

• L'instrument no s'encén: Comproveu la instal·lació de les piles i assegureu-vos que no estiguin esgotades. Substituïu-les si cal.
• Lectures inexactes:
  • Ensure test leads are properly connected and not damaged.
  • Verify the correct measurement mode and output voltage are selected.
  • Consider environmental factors like temperature and humidity, especially for insulation resistance measurements.
• Vol. Alttage warning persists after test: The instrument has an automatic voltage release function. If the warning persists, ensure the circuit under test is fully discharged before handling.
