How do I use the GHT-118 probe?
Connect the BNC end to an oscilloscope with 1 MΩ input impedance. Set the scope to 10x or 100x accordingly. Attach the probe tip to the test point and the ground lead to circuit ground.
What is the maximum input voltage?
The maximum input voltage is 1000V DC + peak AC (CAT II). Do not exceed this limit to avoid damage or injury.
What is the bandwidth of the GHT-118?
The bandwidth is DC to 100 MHz, suitable for high-frequency signal measurement.
Is the GHT-118 compatible with all oscilloscopes?
It is compatible with most oscilloscopes that have a 1 MΩ input impedance and a BNC input. Check your scope's specs.
How do I calibrate the GHT-118?
Calibration is not user-required. For best accuracy, send it to an accredited lab periodically. The probe is factory-calibrated.
What safety precautions should I take?
Always use the probe with the ground lead connected to a known ground. Wear appropriate PPE and follow electrical safety guidelines.
