Hi Hiew,

Don't buy the Sanwa meter because it does not have the x10 K ohm range to check on the FET and to provide accurate testing for diode and zener diode. I have not used the other two types but it seems they are made from the same factory because both have the same type of design cover. Both I believe have the same qualtiy and it depends on your budget on which one you want to choose.

A novice electronics hobbist here.

Need help on purchasing a good and reasonable analog multimeter. I spot three of them but do not know which to choose. Kindly guide me please.

1. Sanwa YX-360TRF
2. Proskit MT-2017
3. Brother HD-390

Is it without the x10k, there are certain components are unable to diagnose? Or could we use an alternative way to test it?

Your guide are greatly appreciated. Thanks.

Hi Paris,

Thanks for the clear explanation.

As far as I know, all analog multimeters present reverse polarity at their probes' terminals for their resistance testing voltages, this being based upon their design. All of them I have used in the past (Central, Palace) up to the one I currently use (Mastech) are working in the same way. Perhaps this has to do with the place of the nulling end for these measurements. In older VTVMs for example, which also included a 1,5V battery for resistance measurements, this Ohms zeroing point adjustment before taking measurements was reversed in comparison to ordinary analog VOMs. Analog VOMs' null point adjustment is done by bringing the needle pointer on the right end side of the panel instrument while VTVMs' Ohms null point was done by bringing it on the left end side of the panel instrument. The point is that after so many years that I abandoned my old (Tech) VTVM, I don't remember clearly the polarity of the testing voltage at the probe output (against the ground). I only think that it was "normal", that is, positive...

HI Woo,

The 1.5 volt batteries is for the x1 Ohm up till x 1 K ohm range and 9volt is for X10 K Ohm range. As for the resistors, the best is to remove one leg out for accurate testing.

Hi Jestine,
Tks for ur reply. Just to reconfirmed with you. Which battery u are referring to? The 1.5 V AA battery or the 9V battery?

Next is about the checking of the resistors in the voltage range, do I have to remove them one by one to test their resistances? Or just check their appearance? Pls brief..tks.

HI Woo,
I have not seen this problem before. I suggest that you make sure the batteries are new and check all the resistors in the voltage range. If the coil is bad it would not go to Infinity.

HI WOO,

The battery is for the power to test components under x10 K ohm. If it is low then under x 10 K ohm you can't calibrate it to zero

Hi Jestine,
Tks for ur prompt respond. When select to ohm, needle will go below the scale from infinity for all the ohm selections. Whereas when selected to other position for ACV, DCV, or DCmA, needle will be at zero point.
Can this be confirm that the needle coil is defective? Is there any quick fix or cure for this defect ? Pls confirm Tks.
