Fluke 1507 Digital Megohmmeter Insulation Resistance Tester User Manual

1. Úvod

The Fluke 1507 Digital Megohmmeter Insulation Resistance Tester is a robust and reliable instrument designed for comprehensive insulation testing in industrial and electrical environments. This manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your Fluke 1507 tester.

Key features include multiple insulation test voltages, automatic calculation of Polarization Index (PI) and Dielectric Absorption Ratio (DAR), a Compare (Pass/Fail) function for repetitive testing, and live circuit detection for enhanced safety.

2. Bezpečnostní informace

WARNING: Always read and understand all safety information before operating the Fluke 1507 tester. Failure to do so may result in serious injury or death.

• Detekce živého obvodu: The tester is equipped with live circuit detection, which prevents insulation tests if a voltage greater than 30 Volts is detected. This feature is crucial for user protection.
• Auto-Discharge: The 1507 provides auto-discharge of capacitive voltage for added user protection after testing.
• Kategorie měření: This instrument complies with ANSI/ISA 82.02.01 (61010-1) 2004, CAN/CSA-C22.2 No. 61010-1-04, and IEC/EN 61010-1 2nd edition for Measurement Category IV 600 V (CAT IV). Always use the tester within its specified measurement category.
• Správné použití: Use only the test leads and accessories supplied or approved by Fluke. Inspect test leads for damage before each use.
• Podmínky prostředí: Do not use the tester in wet or explosive environments. Ensure the operating area is dry and well-ventilated.

4. Nastavení

4.1. Instalace baterie

The Fluke 1507 requires four AA alkaline batteries for operation. These are typically included with the unit. To install or replace batteries:

1. Ujistěte se, že je tester VYPNUTÝ.
2. Vyhledejte přihrádku na baterie na zadní straně jednotky.
3. Pomocí šroubováku otevřete kryt prostoru pro baterie.
4. Insert the four AA batteries, observing the correct polarity as indicated inside the compartment.
5. Nasaďte kryt prostoru pro baterie a zajistěte jej šroubem.

4.2. Připojení testovacích vodičů

Connect the test leads to the appropriate input jacks on the tester. For insulation resistance measurements, use the 'V Ω' and 'COM' jacks. Ensure connections are secure before proceeding with any tests.

5. Návod k obsluze

5.1. Zapnutí/vypnutí

To power on the Fluke 1507, rotate the rotary switch from the 'OFF' position to any desired measurement function. The large, backlit display will illuminate. To power off, rotate the switch back to 'OFF'. The unit also features an auto-power off function to conserve battery life.

5.2. Výběr testovacího objemutages

The Fluke 1507 offers multiple insulation test voltages. Rotate the main rotary switch to the 'INSULATION' section. Then, use the dedicated voltage selection buttons (50 V, 100 V, 250 V, 500 V, 1000 V) to choose the appropriate test voltage pro vaši aplikaci.

5.3. Performing Insulation Tests

Once the desired test voltage is selected and test leads are connected to the circuit under test:

1. Stiskněte a podržte TEST button to initiate the insulation test. The display will show the measured insulation resistance.
2. For hands-free operation during repetitive tests, utilize the remote test probe.
3. The live circuit detection feature will prevent a test if voltage exceeds 30V, indicated by a warning on the display.

5.4. Compare (Pass/Fail) Function

The Compare (Pass/Fail) function simplifies repetitive testing by allowing you to set a pass/fail threshold. Refer to the on-screen prompts and the user interface for setting this function. The tester will then indicate whether the measured resistance meets the predefined criteria.

5.5. Polarizační index (PI) a poměr dielektrické absorpce (DAR)

The Fluke 1507 automatically calculates Polarization Index (PI) and Dielectric Absorption Ratio (DAR), saving time and ensuring accurate assessment of insulation condition. These functions are typically accessed via dedicated buttons on the front panel.

6. Údržba

6.1. Čištění

To clean the exterior of the tester, use a damp cloth and a mild detergent. Do not use abrasive cleaners or solvents. Ensure the unit is completely dry before storage or next use.

6.2. Výměna baterie

Replace batteries when the low battery indicator appears on the display. Refer to Section 4.1 for detailed battery installation instructions. Always use fresh alkaline batteries.

6.3. Kalibrace

For optimal performance and accuracy, periodic calibration by an authorized service center is recommended. Refer to your warranty information or contact Fluke support for calibration schedules and services.
