Top Tronic T48 Multimeter - tested by ZS1JHG

The Top Tronic T48 is a multimeter designed for electronic technicians at an affordable price.In addition to the usual AC,DC Resistance ranges it can also measure Capacitance, Inductance, Frequency to 20Mhz and Temperature. Diodes and transistors can also be tested (via a plug in unit)The multimeter comes with a temperature probe and a neat soft case is available.

The case is covered in a non slip soft plastic and the display is huge with large digits, good as easy to see, bad as you only get a three and half digit readout.The pop-out rear stand is of poor flimsy plastic best not used. The multimeter is wide but does have a waistline for smaller hands to grip it firmly, a plus in my case.The temp sensor was tested against my Weather Station indoors and outdoors and found to agree.The DC voltage ranges up to 20V were checked against a Fluke multimeter and found to agree.The Capacitance was checked against sliver mica standard value capacitors and was within 2% tolerance. Here I found a strange anomaly in that capacitance can only be read to the nearest 10 pfalthough you have a three and half digit display my older version multimeter by Top Tronic goes down to 1 pf, strange but true.The unit is equipped with a bright led backlight that works so well you can

almost use it as a torch at night.The frequency counter was accurate up to 10 Mhz and then up to 20 Mhz within about 5%. Tested against the Fluke multimeter and HF Transceiver. The resistance measurements were checked to the Fluke up to 2M and found to agree within the tolerance range of 0 .8%.The inductance measurements were spot checked with an LCR Bridge and found to be better than the claimed tolerance. 

So in summary apart from the disappointing capacitance readout in the pf range the Top Tronic T48 multimeter performed well and is very good value for its price.
