7-inch color touchscreen, storage for 500 sets of measurement data; power supply: AC 220 V ±10%, 50 ±1 Hz; dimensions: 360 × 290 × 170 mm, weight: 5 kg.
Basic measurement principles?
A differential-frequency test voltage is applied, and voltage, current, and phase are sampled; capacitance or inductance is calculated based on impedance relationships, while parameters such as voltage, current, frequency, impedance, and phase angle are simultaneously output.
Overview of panel ports?
Voltage output, voltage input, and current input terminals; thermal printer; 7-inch LCD; 220V power socket; USB port; serial communication port (optional); and grounding terminal.
Connect thick leads to the large voltage output terminals and thin leads to the small voltage input terminals; ensure the chassis is properly grounded before making connections.
What should be noted before wiring?
Ensure the equipment under test is de-energized, isolated from other live parts, and its casing is reliably grounded before connecting the leads.
After measurement, complete the discharge/exit procedure as prompted by the interface before disconnecting the leads to avoid operating while the equipment is live or subject to induced voltage.
How is data exported?
It features internal storage for 500 data sets, a USB port for exporting data, an optional printer for on-site printing, and a real-time clock for timestamping.
Selecting "Bluetooth" displays a QR code; scanning it with a smartphone allows users to install the companion app to remotely control the instrument and view or upload test data.
FAQ
Q1: What precautions should be taken when disconnecting the leads?
A: After measurements are complete, follow the on-screen prompts to finish the discharge and exit procedures before disconnecting the leads; this avoids operating while the equipment is energized or subject to induced voltage.
Q2: What primary needs does it address?
A: It is designed for on-site capacitance and inductance measurements of substation equipment-such as capacitor banks and reactors-with a focus on intelligent human-machine interaction and data management.
Q3: Why does it offer strong interference immunity?
A: The differential-frequency power source allows the test signal to avoid the power-frequency interference band, ensuring stability and accuracy even in environments with strong magnetic fields.
