Measurements
Volt and frequency
1 VAC is 5% down at 2.5kHz (RMS will not work at the frequency).
Input impedance is about 300kOhm on both AC and DC
Minimum reading for both DCV and ACV is 0.800 volt, below that the meter will switch to ohm or just show ""AUTO"".
Current
9.9A range has a time limit of 3 seconds when current is above 2A
Meter has audible and visual (red led) alarm when probes are connected to AmA terminal and no current is flowing.
AmA range is protected with 10A/250V 3.6x10mm fuse
Ohm, continuity, diode and capacitance
Ohm needs about 0.9s to measure 100ohm
Ohm voltage is 0.67V open and 0.0016mA (1.6uA) shorted
Continuity and ohm is same range.
Continuity is very slow (About 500ms).
Continuity beeps when resistance is below 50ohm.
Miscellaneous
A beeper will sound shortly before the meter turns itself off
Current consumption 1.6mA and 7mA with backlight and flashlight.
Standby current consumption of meter is 0.2uA
Meter works down to 1.6V where display gets unstable, battery symbol turns on at 2.4V
Readings are stable down to about 2V
Backlight changes brightness with voltage and is nearly off at 2.5V.
Viewing angle is a bit limited, especially from the top.
Display updates around 3 times/sec
Backlight and flashlight will stay on for 140 seconds
Will automatic turn power off in about 16 minutes.
The meter usual need a couple of display update to reach the final value.
Standard probes cannot be fully seated (Maybe 3mm stick up)
