Hello.
I have just purchased a BM869s(elma rebrand in scandinavia), and i like it, but i am a bit unsure if something is wrong.
If i simply take the leads put into COM and ohm/v/capacitance and put on table, spaced around 10 centimeters apart, and toggle through the different modes, it does not go to zero, and isnt fully "stable".
I have gone through all settings and written down what happens, so perhaps someone can tell me if something is wrong or not. the probes are not touching eachother, or anything for that matter.
here goes:
first position:
AC voltage mode:
voltage: 5.xx to 0.1v over 10sec
Hz mode:
voltage: 3.xx to 000.1v over 5 seconds
second position:
AC voltage mode:
0.3xx - 0.08xxv over 10 sec
dBm mode:
starts at 4dbM, goes to 2.3x over 5 seconds
hz mode:
starts at 0.09xv goes to 0.083 in 5 seconds
third position:
DC voltage mode:
starts at 0.03xxx and very fast goes to -0.0000v, analog bargraph flipping the second "bar"
AC + DC dual display mode
AC voltage: 0.15x to 0.086v in 5 seconds
DC voltage takes ~5-10 sec to go down to 0.001v
AC+DC + AC dual display mode:
AC starts at ~0.1 and goes to 0.86 over 5 sec
DC+AC starts at 0.51xx and quickly goes to 0.086xv
fourth position:
DC mv mode:
starts at i think ~3mV quickly (1 sec) goes to 0.03mV, bargraph swings 3-4 bars a couple of times pr second
DC+AC dual mv mode:
AC starts at 95.x mV and stays there
DC goes fast to 0.04mV and stays there
DC+AC + AC dual mode display:
AC starts and stays at roughly 95-96mV
DC+AC starts high, and inside of 1 sec jumps to ~94-95.xx mV
Hz mode:
00.000Hz
D% mode:
00.00
fifth position:
AC mV mode:
HZ starts at 50.01Hz, stays there
AC starts at ~150.xxmV and within 1 sec goes to 92.xx mV
Hz/dbm mode:
49.99hz
starts at 4dBm and within 1sec goes to 3.4x
sixth position (temps):
shows nothing on all modes
seventh position:
diod: 0L
capacitance: 00.02nF, instant there, doesnt change
eighth position:
ohms: autoranges down to .0L Mohm normally. same with beeper
conductance: starts at 0.1x and swings around doing down to 0.01nS over a couple of seconds
ninth position:
DC mV:
starts at -00.001, jumps between -00.000. -23.99 to -25 % 4-20. seems proper
DC+AC mA
AC starts at 00.01 mA, goes to 00.00 after a second or so
DC starts at 00.000 and goes to 00.001 after a few seconds.
DC+AC + AC
AC starts at 00.00
DC+AC starts at 6.4xx mA, after 10 seconds settles to 0.004mA
AC:
0.000Hz instantly
AC amperage starts and stays at 00.001mA
tenth position:
starts and zeroes down in at most 1 second on all modes
Thanks
