Product Features:

Portable design, lightweight, easy to operate with one hand, convenient for movement or on-site measurement.

By using innovative proprietary circuit components, we ensure that the equipment performance remains highly reliable even under extreme conditions.

Built in high-precision electric/magnetic field composite sensor with high sensitivity and fast response.

Fully compensated frequency response, providing measurement results.

Real time display of LCD screen, directly displaying the total exposure value within the measured frequency range.

The built-in signal strength prompt speaker (the size of the prompt sound is proportional to the electromagnetic field strength) effectively helps identify the signal source and quickly locate the signal position.

Low battery warning and automatic shutdown function during idle time.

Common fault types and diagnosis:

Power system malfunction:

This is a common type of malfunction, typically manifested as inability to power on, repeated restarts, or screen flickering. When diagnosing, the focus should be on checking whether the output voltage of the switching power module is stable, and whether the capacitors, fuses, and other components in the high-voltage inverter circuit (if present) are damaged.

Local oscillator loss of lock and frequency error:

The fault phenomena include frequency reading jumps, deterioration of phase noise, etc. The core reasons may involve aging of the temperature compensated crystal oscillator, failure of the phase detector or loop filter in the phase-locked loop circuit, and insufficient gain of the microwave amplifier in the local oscillator frequency doubling link. During maintenance, it is necessary to use a high stability frequency meter to measure the stability of the reference clock signal and check the linear variation of the PLL control voltage.
