As an update, because I was bored. I decided to do some resistance and capacitance measurements. I have some 0.1% metal film (or metal foil they use different names in different places) resistors from KOASpeer. I decided to test their resistance. The ones tested were either 1/3W or 1/4W resistors, though I did have 1/2W 0.1% resistors for 3 of the values. I did a spot check on these 1.2W resistors and they fell exactly in line with the values recoreded for the lower wattage varieties.

33.2K ohm

So actual value can range from 33.17K to 33.23K ohms.

The meters rated accuracy in this range is +/-0.5%. Which is a range of 33.03K to 33.37K

Resistor 1 reading: 33.09K

Resistor 2 reading: 33.09K

Resistor 3 reading: 33.09K

Resistor 4 reading: 33.08K

Resistor 5 reading: 33.09K

Resistor 6 reading: 33.10K

Resistor 7 reading: 33.09K

Resistor 8 reading: 33.08K

Resistor 9 reading: 33.09K

Resistor 10 reading: 33.09K

This gives an average reading of 33.089K which is (assuming the resistors are 33.2K) -0.334%. Which is well within the listed accuracy of the meter. Even assuming the worse case scenario of ALL of the resistor being 33.23K, the error is just -0.434%. The precision of both the meter and the resistors is surpisingly good too.

Next up is a 33.0K resistor.

The resistors would fall within the range of 32.967K to 33.033K

0.5% rated meter accuracy means the resistors should fall within 32.835K to 33.165K

Resistor 1: 32.89K

Resistor 2: 32.90K

Resistor 3: 32.90K

Resistor 4: 32.90K

Resistor 5: 32.90K

Resistor 6: 32.90K

Resistor 7: 32.89K

Resistor 8: 32.89K

This gives an average reading of 32.8975K which is (assuming the resistors are 33.2K) an error of -0.311%. Which is well within the listed accuracy of the meter. Even assuming the worse case scenario of ALL of the resistor being 33.033K, the error is just -0.410%. Once again the precision of the meter AND the resistors is quite good.

Next one is a 2K resistor:

The resistors would fall within the range of 1.998K to 2.002K

0.5% rated meter accuracy means the resistors should fall within 1.990K to 2.010K

Resistor 1 reading: 1.9947K

Resistor 2 reading: 1.9950K

Resistor 3 reading: 1.9948K

Resistor 4 reading: 1.9946K

Resistor 5 reading: 1.9951K

Resistor 6 reading: 1.9949K

Resistor 7 reading: 1.9949K

Resistor 8 reading: 1.9948K

Resistor 9 reading: 1.9946K

Resistor 10 reading: 1.9947K

This gives an average reading of 1.9948K which is (assuming the resistors are 2.0K) an error of -0.2595%. Which is well within the listed accuracy of the meter. Even assuming the worse case scenario of ALL of the resistor being 2.002K, the error is just -0.3591%. Once again the precision of the meter AND the resistors is quite good.

Next up are some 220K resistors. This is interesting because it falls on the edge of two ranges. 220Kohm which has a +/- 0.5% accuracy and 2.2Mohm which has a +/- 0.8% accuracy. I will list the 220Kohm range readings first then the 2.2Mohm range readings for the same resistor in parentheses following.

The resistors would fall within the range of 219.78K to 220.22K

0.5% rated meter accuracy for the 220Kohm means the resistors should fall within 218.90K to 221.10K

0.8% rated meter accuracy for the 2.2Mohm range means the resistors should fall within 0.21824M to 0.22175M

Resistor 1: 219.67K (0.2192M)

Resistor 2: 219.69K (0.2193M)

Resistor 3: 219.68K (0.2193M)

Resistor 4: 219.68K (0.2193M)

Resistor 5: 219.68K (0.2192M)

Resistor 6: 219.65K (0.2192M)

Resistor 7: 219.67K (0.2192M)

Resistor 8: 219.68K (0.2192M)

Resistor 9: 219.69K (0.2192M)

Resistor 10: 219.68K (0.2192M)

This gives an average reading of 219.68K(0.21923M) which is, assuming the resistors are 220K(0.220M), an error of -0.147%(-0.350%). Which is well within the listed accuracy of the meter. Even assuming the worse case scenario of ALL of the resistor being 220.22K (0.2202M), the error is just -0.247%(-0.4495%). While clearly the 220k range appears to have better accuracy, the 2.2Mohm range still falls within the accuracy listed for the 220K range, which is better than its own.

In summary, the meter appeared to do better than its rated accuracy which is what you would hope for something fresh from the factory.

Next up its capacitance time. To be honest I am not sure how to handle the errors of the capacitors. Often their listed range is larger than the range of the meter. My guess is just treat them as their nominal value and roll with it. For the sake of honesty I include the worst case scenario value as well.

First up are some Panasonic ECG Stacked Metal Film capacitors. They are rated 100V and 0.1uF +/-5%. The meter is rated at +/-3% in this range. The meter reads in nF in this range so the values should center around 100nF

The values for capacitance could range 0.95uF to 1.05uF

The meter should read 97.00nF to 103.00nF or a .06uF range.

Capacitor 1: 99.20nF

Capacitor 2: 101.17nF

Capacitor 3: 101.22nF

Capacitor 4: 99.27nF

Capacitor 5: 99.99nF

Capacitor 6: 100.36nF

Capacitor 7: 101.68nF

Capacitor 8: 99.28nF

Capacitor 9: 101.06nF

Capacitor 10: 99.66nF

THis gives an average value of 100.289nF which is an error of 0.289% from the expected value. In a worse case scenario where all were 105nF, the error becomes -4.48%. This is still within the error range of the capacitors themselves. So the meter does well.

Next up are some enormous UnitedChemicon 100V 2200uF caps. These things are 50mm long and 20mm wide. So 0.86 inches wide and about 2 inches tall. The meter uses the 2.2 mF (millifarad) range, which is the last one which is makes an accuracy claim for. It claims 4% accuracy.

These like most electrolytics have a +/- 20% rating.

Capacitor 1: 2.1790mF

Capacitor 2: 2.1764mF

Capacitor 3: 2.1758mF

Capacitor 4: 2.1787mF

Capacitor 5: 2.1756mF

THis gives an average value of 2.1771mF which is an error of 1.041% from the expected value. In a worse case scenario of an extreme 2.64mF, the error becomes -17.53%. This is still within the error range of the capacitors themselves. So the meter does well.

Lastly, I have some ESC (or SC) brand crap capacitors rated at 25V 120uF. These are the type of caps you expect to find spewing their guts everywhere in a PSU or in the VRM of a motherboard. I can't find out anything about them but my guess is like other cheap/basic capacitors they are rated at 20%.

Capacitor 1: 126.70uF

Capacitor 2: 127.00uF

Capacitor 3: 125.15uF

Capacitor 4: 128.28uF

Capacitor 5: 126.16uF

Capacitor 6: 127.01uF

Capacitor 7: 127.23uF

Capacitor 8: 129.54uF

Capacitor 9: 126.44uF

This gives an average value of 127.06uF which gives an error of 5.88%. The worst case scenario error is 32.35%. I really believe because of the suspect nature of these caps. The readings are fine, but the error falls with the caps themselves. If you notice they don't have nearly as precise values as the rest of the quality components I have measured. The massive 2200uF cap was consistant into the third digit, where these vary wildly.

So in summary, it seems that the meter is definitely capable of meeting its specified accuracy.
