Hello everyone,
As you see ,This is my first post in this forum,but i'm reading this forums for many years. This my search progress and mini-review about Victor VC97 Multimeter (4000 Count). Hopefully it helps someone.
I had a cheap chinese M890G Multimeter for more than 12 years (for my own personal hobby projects) and this multimeter worked excellent. The most important problem about it was its input protection, which finally caused the death of the multimeter.
I was searching for cheap multimeter because the highest voltage that i use , is 220V main voltage and for my hobby projects, i don't need the Agilent, Fluke or ... I saw these 2 videos on youtube :
Which compare Vichy VC97 vs Victor VC97. After seeing these 2 videos and some other online videos i liked the victor vc97 more. So i decided to buy it. I found their homepage and online store :
http://www.victor-multimeter.com/products/digital-multimeter/victor-vc97-3-3-4-digital-multimeter-676.html it seems that they updated this model and it was on sale for 18$.The most important new feature is TRUE RMS measurement, which is very good at this price ! After searching my local shops , i found this multimeter on sale even cheaper for 16.3$! so , i bought it and here it's the mini Review :
I tested this multimeter at my work place with a ESCORT 179 multimeter and a KYORITSU KEW1062.
BTW, in their homepage, they didn't update some info about this multimeter:
1) in website you can only see the TRUERMS in the picture 2) Bandwidth of AC measurement in website is 40-400Hz, but in the manual is upto 1KHZ(which is correct) 3) the battery in website and in the manual is 2x1.5V ,but actually it is 1x9V! 4) on the site Capacitance measurement is upto 200uf , but in the manual is upto 100mF (100000uF)! 5)on the website there is nothing about the display backlight 6) on the website they say it has bargraph which it doesn't!
This multimeter comes with the normal chinese probes, an adapter for transistor/capacitor measurements and a simple temperature probe and a 1 page manual!
The tests :
1) DC Voltage : I tested from 50mv upto 150V DC. The accuracy was almost excellent.it says 0.5%+4d in manual, but in my tests was about 0.3%.
2) AC Voltage : I tested from 0.5V ... 220V(50 HZ) and 380V (3phase Voltage). Its accuracy was better than 0.8%+10d (according to manual). Bandwidth was about 1100Hz.I tested the bandwidth with function generator @ 1V amplitude.
3)DC A : I tested from 100uA to 350mA. It was well in the range and accuracy was better than 1.2%.
4)AC A : didn't test it.
5)Resistance : accuracy was better than 0.8%+4d (according to manual).
6) Capacitance : Tested it with 1000uF Capacitor and the error was less than 5%.
7)Frequency : tested upto 16MHz. accuracy was better than 0.5%+10d (according to manual).
8)Buzzer : Very fast and also Latched!
9)Diode test : Was very Good! Diode test voltage is around 3V!
I opened it and took some pictures :
You can see it stated CAT IV 600V and Maximum DC 1KV on the multimeter. It has 2 fuses, a 400ma fuse (simple cheap glass fuse) and a 10A fuse (Ceramic Fuse-no brand name). Both fuses are rated for 250V.There is also a PTC on board, but they mounted it under display.
The Negative points :
1)in the mv range : if the probes are open circuit, display is going too high around +100mv or -100mv (which i don't like), but i measure a voltage about 50mv around a 2Mohms resistor and it works fine.
2)if you have AC+DC voltage in AC mode and DC Part of the voltage goes higher than 8 or lower than -8V the multimeter shows wrong.
3)in both AC measurement and Frequency measurement , if your wave for has a DC offset which is more than a certain value (depends on the amplitude of AC Part), the frequency measurement shows 0!
Finally i'm very satisfied with my purchase and hope this multimeter works as good as my M890G!
