Tools and Hardware Reviews of TekPower TP4000ZC PC based RS232-Interaced Auto Ranging Digital Multimeter
Customer Review: OK for the price
Summary: 3 Stars
My First impressions:
Positive things:
Meter uses two "AA" size batteries (I don't like 9V batteries!)
Meter is an auto ranging meter (not manual ranging like cheaper meters). Input impedance is 10 MOhm and has a 3-3/4 digit display.
RS232 connectivity sounds like an interesting feature, although I have not tested it yet
Meter comes with rubber slip-on protector (Like another reviewer pointed out it's red instead of yellow). The slip-on has holders on the back for the probes to clip onto for storage (although the leads would still dangle around)
Meter also comes with probes, thermocouple for temp measurements, RS232 cable, software CD and "generic" batteries (although the first thing I would do is replace the included batteries with alkaline AAs)
Meter can measure:
AC/DC voltage, AC/DC current up to 10 amps, Resistance up to 40 MOhms, Diode test, Continuity, Temperature
Capacitance up to 100uF. Note that the manual warns it may take up to 15 seconds to test/display a 100uF capacitor. Some other meters can measure higher value capacitors > 100uF, although I think testing large electrolytic capacitors with any multimeter may not give accurate results. (I have seen bad electrolytic caps test good with the cap test on multimeters)
Frequency 10Hz to 10MHz (according to the manual) as well as Duty Cycle (0.1% to 99.9%)
The case quality and buttons are better than I expected, I don't think the build quality is bad for the price.
Negative things:
The continuity beeper is too quiet, especially in noisy environments.
The LCD display is NOT backlit. This is a drawback if you work in dark places as the display would be unreadable unless holding a flashlight but your two hands are typically holding the probes.
The "instruction manual" is a joke. It's a folded piece of paper, with really small print. However if you're considering buying this you most likely know how to use a multimeter.
Overall it's an OK meter for the price. If you know how to use a multimeter and only occasionally need to use one this one will probably fit the bill. If you use one on a more-or-less daily basis, in noisy or dark places then you might consider a better (more expensive) meter.
A slightly more expensive alternative to this TekPower meter is Mastech AC/DC Auto/Manual Range Digital Multimeter, MS8268
This Mastech meter appears to have a backlit display, can test hFE (transistor gain) which the TekPower cannot, and has an input jack warning feature so you have some protection against doing something dumb like trying to measure voltage with the probes in the current measurement jacks (if you do this you may blow the meter's internal fuse and will have to open it up to replace it)
