FAQ, following questions will help you to select the matched probe
for your applications.
1. Please determine if you are measuring AC or DC?
GFUVE Q20B-3 is for AC measuring. If DC, we have hall effect models
to suggest.
2. What is the maximum current you will measure?
Q20B-3 max current is 200A
3. What size conductor will you clamp onto? This parameter
determines the probe jaw size needed.
Q20B-3 can clamp conductor φ40mm
4. What type of probe output do you need or can you work with (mA,
mV, A, AC, etc.)?
Q20B-3 can customize output with Milliampere, Millivolt.
5. What is the working voltage of the conductor to be measured?
GFUVE probes should be used below 600 volts
6. What type of termination do you need: jacks, leads or BNC?
Q20B-3 standard has 2.5meter leads. We can offer jacks or BNC… as
options.
