5. Əməliyyat Təlimatları

5.1 Ümumi əməliyyat

• Yandırma/Söndürmə: Rotate the function switch from OFF to any desired measurement function to turn the meter on. Rotate back to OFF to power off. The meter also features an Auto Power Off function to conserve battery life.
• Avtomatik diapazon: The ESI 590 Pro is an auto-ranging DMM, meaning it automatically selects the appropriate measurement range. This simplifies operation, but some measurements may take a moment to stabilize.
• Arxa işıq: Press the backlight button (often integrated with the HOLD button or a separate button) to illuminate the display for better visibility in low-light conditions.
• Məlumat saxlama: düyməsini basın BAXIN button to freeze the current reading on the display. Press it again to release.
• Relative Change Function (REL): düyməsini basın REL button to store the current reading as a reference value. Subsequent readings will be displayed as the difference from this reference. Press again to exit relative mode.

5.2 Ölçmə Funksiyaları

Select the desired function by rotating the central switch.

• Cildtage (V DC/AC): Connect leads as described in Section 4.2. Select the V DC or V AC position on the rotary switch. The meter will auto-range.
• Current (A DC/AC, mA DC/AC): Connect leads to the appropriate current jacks (mA or 20A) and select the corresponding current function on the rotary switch. Ensure the meter is connected in series with the circuit.
• Müqavimət (Ω): Connect leads to COM and VΩHz. Select the Ω function. Ensure the circuit is de-energized before measuring resistance.
• Capacitance (CAP): Connect leads to COM and VΩHz. Select the CAP function. Discharge capacitors before testing.
• Frequency (Hz) / Duty Cycle (%): Connect leads to COM and VΩHz. Select the Hz/% function.
• Temperatur (°C/°F): Connect the temperature probe to the appropriate jacks (usually COM and VΩHz, or dedicated temperature jacks if present). Select the °C or °F function.
• RPM (dəqiqədə inqilablar): Use the inductive RPM pick-up. Connect it to the designated RPM input. Select the RPM function. The inductive pick-up features a five-position adjustable sensitivity switch for optimal signal detection.
• Ms Pulse Width: This function is specifically designed to measure the on-time of fuel injectors. Connect the meter according to the specific instructions for pulse width measurement (refer to advanced automotive diagnostics guides if needed). Select the Ms-PULSE function.

6. Baxım

6.1 Təmizləmə

Sayğacın qutusunu reklamla silinamp cloth and a mild detergent. Do not use abrasives or solvents. Keep the display clean and free from scratches.

6.2 Batareyanın dəyişdirilməsi

When the low battery indicator appears on the display, replace the 9-volt battery as described in Section 4.1. Prompt battery replacement ensures continued accuracy and proper operation.

6.3 Sigortanın dəyişdirilməsi

The ESI 590 Pro DMM is protected by internal fuses for current measurement ranges. If the meter fails to read current, the fuse may be blown. Refer to the meter's internal markings for fuse specifications (e.g., 20A fused, 400mA fused) and replace with fuses of identical type and rating. Fuse replacement typically involves opening the meter's back casing, similar to battery replacement, but may require additional steps. Consult a qualified technician if unsure.

6.4 Saxlama

When not in use for extended periods, store the meter in its carrying case in a cool, dry environment. Remove the battery if storing for several months to prevent leakage.

7. Giderme

• Sayğac işə düşmür: Batareyanın quraşdırılmasını yoxlayın və batareyanın kifayət qədər doldurulduğundan əmin olun. Lazım gələrsə dəyişdirin.
• Inaccurate or unstable readings:
  • Test naqillərinin düzgün bir şəkildə qoşulduğundan və yaxşı təmasda olduğundan əmin olun.
  • Düzgün funksiyanın və diapazonun seçildiyini yoxlayın.
  • Check for external electrical interference.
  • Allow the auto-ranging function sufficient time to stabilize, especially for initial readings.
• Ekranda 'OL' (Artıq yükləmə) göstərilir: This indicates the measured value exceeds the selected range. For auto-ranging meters, it means the value is beyond the meter's maximum capability for that function. Ensure the meter is connected correctly and the value is within the meter's specifications.
• No current reading: Check the fuses as described in Section 6.3. Ensure the test leads are connected to the correct current input jacks (mA or 20A) and the meter is in series with the circuit.
• Tachometer not working correctly: Ensure the inductive RPM pick-up is properly connected and positioned. Adjust the five-position sensitivity switch on the pick-up to optimize signal detection. Verify the engine is running and producing a consistent signal.
