Field effect tube separation tester is mainly used for small and medium-sized electronic products enterprises to field effect tube or IGBT batch measurement, screening
1, the adoption of high precision AD, meet the measurement accuracy, and high-speed microprocessor and electronic switch, so that the measurement work quickly, efficient, quiet. The international advanced pulse measurement method can provide more than 10A~ 75A test current, without heating the measured pipe. Automatic current sharing function to ensure the safety of the tube under test
2, with self-check function, measurement and judgment function and fault alarm indicator function, when not Vmos tube or wrong insertion, measurement can not continue. Before and after the measurement, the measuring socket grid source is in a short circuit state to ensure the safety of the measured tube when inserting or pulling out the tube seat
3, there are 20A~150A capacity selection, even if the wrong current with the maximum current measurement of small capacity pipe, will not damage the tube under test
4. You can set the range of sorting parameters as required. The lower and upper limits of the on voltage Ut, transconductance Gfs, on-state resistance Ron, and interelectrode capacitance Cir can be set. For the measurement beyond the limit, the buzzer will alarm, and which parameter beyond the limit, will flash prompt, the user can ignore the specific data in line with the standard parameters, only pay attention to the flashing parameters when the alarm, which greatly convenient industrial batch measurement
5, simple to use, do not need professional knowledge
Two, the main indicators:
1. The measuring VMOS tube can simultaneously disy:
On-state resistance Ron 1~999mΩ (when it exceeds 999mΩ, it automatically switches to 9.99Ω stop)
Transconductance Gfs 0~99.9S
Starting voltage Ut 1~7.5V
Electrode capacitance Cir 0.1~9.9 (np)
2, if you need, through the auxiliary function key, you can also get:
a,Cir 1percent nP accuracy;
b,Ut 1percentV precision;
c, Ids(max A),Vds(min V);
d, and when measuring Ggs: Ids(A),Vds(V),Vgs(V);
3, 10-bit LED disy.
4, the use of industrial switching power supply, can work normally in 160V~230V
On-state resistance Ron 0~999mΩ accurate to 1mΩ
(When it exceeds 999 mΩ, it automatically switches to 9.99 Mω)
Transconductance Gfs 0~99.9S accurate to degree 10percent S
Open voltage Ut 0~8.0V accurate to 10percent V
Electrode capacitance Cir 0~9.9 (np) accurate to 10percent np
If you want, you can also get: -- through the auxiliary key
a,Cir 1percent nP accuracy; Ut 1percentV accuracy;
b, Ids(max A),Vds(min V);
c, and when measuring Ggs: Ids(A),Vds(V),Vgs(V);
Three, chassis:
Aluminum alloy cold - drawn te as the frame, adjustable foot. Workbench has 220 and 3P sockets. Panel features capacity selection, as well as 220/3P selection.

Size: 240*350*130mm (width * depth * height)

Four, measurement examples: (Test conditions can be obtained by pressing the auxiliary key)
Example 1: IRF3205
Ron 5m test condition: Ids=74.6A,Vds=0.44V
Cir 3.14nP test conditions: Vgs=0,Vds=10V
Ut 2.91V test conditions: Vds=10V,Ids=1mA
Gfs 27.9S 测试条件：Ids=35.5A,Vds=6.44V,Vgs=5.15V
