4.1 Function Switch and Auto Ranging

Turn the rotary switch to the desired measurement function. The DT-9516 is an auto-ranging multimeter, meaning it automatically selects the appropriate measurement range for the input signal, simplifying operation.

Figure 4: The multimeter's auto-ranging feature allows for intuitive operation without manual range selection.

4.2 Awọn iṣẹ wiwọn

The DT-9516 offers a wide range of measurement capabilities:

• Voltage (AC/DC): Select the 'V' position on the rotary switch. The meter will automatically detect AC or DC voltage.
• Current (AC/DC): Select the 'mAµA' or '10A' position. Ensure test leads are connected to the correct current input jacks.
• Agbára ìdènà (Ω): Select the 'Ω' position.
• Capacitance (CAP): Select the 'CAP' position.
• Frequency (Hz%): Select the 'Hz%' position.
• Idanwo Diode: Select the diode symbol position.
• Itesiwaju: Select the continuity symbol position. An audible tone indicates continuity.
• Iwọn otutu: Select the temperature symbol position. This function typically requires a K-type thermocouple (sold separately).

4.3 Awọn iṣẹ pataki

• Iṣẹ VFD: The Variable Frequency Drive (VFD) function utilizes a low-pass filter for accurate measurement of VFD signals. Select the 'VFD' position on the rotary switch.

Figure 7: The VFD function enables precise measurement of variable frequency drive signals.
• Idaduro data (HOLD): Tẹ awọn DIMU button to freeze the current measurement on the display. Press again to release. This is useful for recording readings in difficult-to-view awọn ipo.


Figure 8: The Data Hold function allows users to lock and record measurement values with a single button press.

• O pọju/MIN: Tẹ awọn MAX/MIN button to record the maximum and minimum values during a measurement session.
• REL (Ìwọ̀n Ìbátan): Tẹ awọn REL button to store the current reading as a reference value. Subsequent measurements will be displayed as a deviation from this reference.
• Imọlẹ ẹhin: Press the backlight button (often integrated with another function or a dedicated button) to illuminate the display for better visibility in low-light conditions.

5.2 Batiri Rirọpo

When the battery indicator appears on the display, replace the batteries as described in Section 3.1. Always use three new AAA batteries.

5.3 Fiusi Rirọpo

If the current measurement functions cease to operate, the internal fuses may need replacement. Refer to the safety section for fuse specifications (10A/1000V and 0.8A/1000V). Fuse replacement should only be performed by qualified personnel.

Warning: Disconnect all test leads from the meter and any circuit before opening the case for battery or fuse replacement.
