Most meters have a high impedance on low DC volt and mV ranges (2.5GOhm) to prevent loading low voltage circuits. Could someone confirm that the Brymen 869 has the same feature? All I can find is 10MOhm on those ranges (Brymen site).
The docs are probably wrong, as Brymen owners would have complained about it by now.
It's actually 10Mohm for all ranges as written in docs, verified on mine 896S right now.
I was aware about that before purchase, so i do not complian.
Fluke's 87V standard voltage reading loads 10Mohm as well, the "high impedance mode" is only for 500mV range and is
unspecified for both actual impedance and precision (and has to be engaged with a key press on DMM's turn-on).
My meter's rotary switch is on the stiff side but still acceptable, no problem with beep sound level and instrument size, both are comfortable to me (and yes, my hearing is good).
I often use the double temperature reading function with differential readout, a neat feature not found in most competitor devices.
I found AC TrueRMS voltage reading very accurate in audio freq. range as well as DC current accuracy and resolution on both 10A and 0.6A ranges.
What i dislike is the LCD backlight, quite uneven on left side, plus the PC cable interface that miss standard USB COM profile adopting a bugged HID interface mode (it fails when you attempt ot import it under NI-VISA standard HID driver profile) and a ridiculous way to transmit the DMM readings (display's segments bit mapping
), that translates into a huge PITA when you have to write your own logger application.
But considering Fluke's ripp-off EU street's prices (official distributors please, not buy&die ebay sellers), i'm happy to have spent 230E (VAT included) for this one.
