The Brymen BM857s is a True RMS digital multimeter and offers functionalities such as dBm, a high-resolution mode, Max-Min values, Crest and much more.
With the 500,000-count display of this multimeter you can measure DC voltages with a 0.03% accuracy. The meter has a Crest functionality that automatically displays the peak value. The display offers back light and because of this, values can always be read easily. The display updates every 5 seconds with a new measurement. In addition, the display has an analogue bar graph that updates 60 times per second and thus indicates clearly how the measured values are in ratio of time.
The multimeter has 3 display possibilities. 999,999 counts can be shown on the display for frequency, for DCV 500,000 counts and for other measurements 50,000 counts. The 500,000-count mode has a lower update speed of 1.25 updates per second. The 50,000-count mode will on average update 5 times per second.
The BM857s also has UL safety certification and CAT-III insulation of 1,000 V. The building quality of this multimeter is very high; the fuses in the meter are of a very high quality and can be replaced easily if necessary.
The meter also offers some additional useful functionalities such as the detection that is built in to offer protection against the incorrect connection of the test leads and the meter also has a 50/60 HZ filter to filter out the static coming from the electricity network. The K-type thermocouple that comes with the multimeter, can easily measure temperatures. In addition, the BM857s also has a Lo-Z mode which makes it possible to prevent ghost voltages at particular measurements.
