Row.
Stress_responsive genes are divided into two methods of non-on-line testing and on-line testing at present.Wherein, non-on-line testing method refers to
Using portable tester, irregularly harmonic source of interest is tested.Device used in stress_responsive genes is surveyed for harmonic wave
Try instrument.
However the current clamp heavier mass in stress_responsive genes instrument, since current clamp includes copper coil, weight itself is
It is difficult to mitigate, and stress_responsive genes need current clamp being clipped in terminal block current line.Since current clamp is heavier, the testing time compared with
It is long, it is easy to cause current clamp and drags out current line from terminal block, and then terminal block is caused to damage or occur even more serious
Accident, after a protracted use, heavier current clamp can cause certain abrasion to the wire surface that end is connected, and cause
Bad consequence.
