• MAX/MIN Key: Records maximum and minimum values during a measurement session.
• REL Key: Activates relative measurement mode.
• Hz/DUTY Key: Selects frequency or duty cycle measurement.
• Input Jacks (COM, T+VΩHz): Connect test leads for voltage, resistance, capacitance, diode, continuity, and temperature measurements.

5. Setup

5.1. Battery Installation

The AP-570C requires one 9V (6F22) battery. To install or replace the battery:

1. Ensure the meter is turned OFF.
2. Use the provided small screwdriver to open the battery compartment cover on the back of the meter.
3. Insert the 9V battery, observing the correct polarity (+/-).
4. Replace the battery compartment cover and secure it with the screw.

5.2. Connecting Test Leads

For most measurements (voltage, resistance, capacitance, diode, continuity, temperature), connect the test leads:

• Insert the black test lead into the "COM" (common) input jack.
• Insert the red test lead into the "T+VΩHz" input jack.
• For temperature measurements, connect the temperature probe to the same input jacks, ensuring correct polarity if applicable.

6. Operating Instructions

6.1. AC/DC Current Measurement (Clamp)

The clamp function allows for non-contact current measurement. This is ideal for safely measuring current in live circuits.

1. Turn the rotary switch to the desired current range (e.g., 400A or 1000A).
2. Press the SELECT button to toggle between AC and DC current measurement if necessary.
3. Open the clamp jaws by pressing the trigger.
4. Enclose a single conductor (not a bundle of wires) within the clamp jaws. Ensure the jaws are fully closed.
5. Read the current value on the LCD display.

6.2. AC/DC Voltage Measurement

To measure voltage, use the test leads connected to the appropriate input jacks.

1. Turn the rotary switch to the "V~" (AC Voltage) or "V-" (DC Voltage) position. The meter may auto-range.
2. Connect the test leads in parallel to the circuit or component you wish to measure.
3. Read the voltage value on the LCD display.

6.3. Resistance, Capacitance, Diode, and Continuity Measurement

These functions are accessed via the rotary switch and SELECT button.

1. Turn the rotary switch to the "Ω" (Resistance), "CAP" (Capacitance), or "Diode/Continuity" position.
2. Use the SELECT button to switch between Diode Test and Continuity Test if on the combined setting.
3. Connect the test leads across the component to be measured.
4. Read the value on the LCD display. For continuity, a buzzer will sound if continuity is detected.

6.4. Temperature Measurement

The AP-570C can measure temperature using the included temperature probe.

1. Turn the rotary switch to the "°C" (Temperature) position.
2. Connect the temperature probe to the "COM" and "T+VΩHz" input jacks.
3. Place the tip of the temperature probe on or in the object whose temperature you wish to measure.
4. Read the temperature value on the LCD display. The range is -20°C to 1000°C.

6.5. Backlight and Data Hold

• Backlight: Press the "D.HOLD/Back Light" button briefly to turn the LCD backlight on or off, improving visibility in low-light conditions.
• Data Hold: Press and hold the "D.HOLD/Back Light" button to freeze the current reading on the display. Press again to release.

6.6. Non-Contact Voltage (NCV) Detection

The NCV function allows for quick detection of AC voltage without direct contact.

1. Turn the rotary switch to the "NCV" position.
2. Move the top part of the meter (near the clamp jaws) close to the conductor or outlet.
3. The meter will indicate the presence of AC voltage through an audible beep and/or visual indicator.

If you encounter issues with your AP-570C, consider the following common solutions:

• No Display/Faint Display: Check battery charge and ensure it is correctly installed. Replace if necessary.
• "OL" on Display: Indicates an over-range condition. The measured value exceeds the selected range. Switch to a higher range or verify the circuit.
• Inaccurate Readings:
  • Ensure test leads are fully inserted and making good contact.
  • Verify the rotary switch is set to the correct function and range.
  • For current measurements, ensure only one conductor is within the clamp jaws.
  • Check for external electromagnetic interference.
• Continuity Buzzer Not Working: Ensure the meter is in continuity mode and test leads are making proper contact. If the issue persists, the meter may require service.
