The Simpson 260-8P Analog Multimeter features a classic design optimized for clear readings and durable performance. Key components include the meter movement, range selector switch, and input jacks.

Obrázok 1: Predné view of the Simpson 260-8P Analog Multimeter. This image displays the large analog meter dial, the central rotary range selector switch, and the various input jacks located at the bottom and sides of the unit. A carrying handle is visible at the top.

3.1. Komponenty

• Analog Meter Dial: Displays measurement values using a needle against a calibrated scale. Features a mirrored scale to reduce parallax error.
• Range Selector Switch: A rotary switch used to select the desired measurement function (ACV, DCV, DCA, Ohms) and range.
• Vstupné konektory: Terminals for connecting test leads. Typically includes common (negative) and positive input jacks for various measurements.
• Zero Ohms Adjustment: A control used to zero the meter before making resistance measurements.
• Ochrana proti preťaženiu: Internal relay and fusing system to protect the meter movement from excessive current or voltage.

4. Nastavenie

4.1. Vybalenie a kontrola

Carefully remove the multimeter and its accessories from the packaging. Inspect all components for any signs of damage. If any damage is found, do not use the device and contact your supplier.

4.2. Inštalácia batérie

The Simpson 260-8P requires 1.5V and 9V batteries for operation, particularly for resistance measurements. Refer to the battery compartment cover (usually on the back or side) for specific battery types and polarity. Ensure batteries are installed correctly.

4.3. Pripojenie testovacích káblov

The multimeter comes with probe test leads equipped with alligator clips. Connect the black test lead to the COMMON (negative) jack and the red test lead to the positive (+) jack appropriate for your measurement type (e.g., for voltage, resistance, or current).

5. Návod na obsluhu

Before making any measurement, ensure the multimeter is set to the correct function and range. Always start with a higher range and decrease if necessary to avoid overloading the meter.

5.1. Reading the Analog Scale

The Simpson 260-8P features a large, multi-colored scale. Identify the correct scale for your selected function and range. The mirrored strip on the scale helps eliminate parallax error: align your eye so that the needle and its reflection are superimposed.

5.2. Meranie jednosmerného napätiatage (DCV)

1. Connect the black test lead to the COMMON jack and the red test lead to the positive (+) jack.
2. Set the range selector switch to the desired DCV range. If the voltage is unknown, start with the highest DCV range.
3. Pripojte testovacie sondy paralelne k meranému komponentu alebo obvodu.
4. Prečítajte si svtage value from the appropriate DCV scale on the meter dial.

5.3. Meranie AC objtage (ACV)

1. Connect the black test lead to the COMMON jack and the red test lead to the positive (+) jack.
2. Set the range selector switch to the desired ACV range. If the voltage is unknown, start with the highest ACV range.
3. Pripojte testovacie sondy paralelne k meranému komponentu alebo obvodu.
4. Prečítajte si svtage value from the appropriate ACV scale on the meter dial. The Simpson 260-8P has an AC frequency response up to 100 kHz.

5.4. Measuring DC Current (DCA)

CAUTION: Never connect the multimeter in parallel for current measurements. Always connect in series with the circuit.

1. Vypnite napájanie obvodu.
2. Connect the black test lead to the COMMON jack and the red test lead to the appropriate current jack (e.g., for mA or A).
3. Set the range selector switch to the desired DCA range. Start with the highest range if the current is unknown.
4. Otvorte obvod, v ktorom sa má merať prúd, a zapojte multimeter do série.
5. Obnovte napájanie obvodu.
6. Read the current value from the appropriate DCA scale.
7. Vypnite napájanie before disconnecting the multimeter and restoring the circuit.

5.5. Meranie odporu (ohmy)

UPOZORNENIE: Pred meraním odporu sa uistite, že obvod je bez napätia a všetky kondenzátory sú vybité.

1. Connect the black test lead to the COMMON jack and the red test lead to the positive (+) jack.
2. Set the range selector switch to the desired Ohms (Ω) range.
3. Zero Ohms Adjustment: Short the test leads together. Adjust the "Zero Ohms" knob until the needle points exactly to zero on the Ohms scale. This step must be performed for each resistance range selected.
4. Pripojte testovacie sondy k meranému komponentu.
5. Read the resistance value from the Ohms scale.

5.6. Ochrana proti preťaženiu

The Simpson 260-8P features relay-protected circuitry and high-energy overload fuses. In case of an overload, the internal protection system will activate to prevent damage to the meter movement. If an overload occurs, disconnect the meter, check the circuit, and reset the meter if necessary (refer to specific instructions in the full manual if available, or contact support).

6. Údržba

6.1. Výmena batérie

When the meter's accuracy for resistance measurements begins to degrade, or if the needle cannot be zeroed on the Ohms scale, it is likely time to replace the internal 1.5V and 9V batteries. Refer to the battery compartment for access and ensure correct polarity during replacement. Use only specified battery types.

6.2. Upratovanie

Clean the exterior of the multimeter with a soft, damp handričkou. Nepoužívajte abrazívne čistiace prostriedky ani rozpúšťadlá. Pred čistením sa uistite, že je zariadenie vypnuté a odpojené od všetkých obvodov.

6.3. Výmena poistky

The Simpson 260-8P is equipped with high-energy overload fuses. If the meter ceases to function on a particular current or voltage range after an overload event, a fuse may need replacement. Fuse replacement should only be performed by qualified personnel. Refer to the full service manual for fuse specifications and replacement procedures.

7. Riešenie problémov
