Display Indicators
Lights up when data is being held. (p.33)
Lights up in function mode. (p.50)
Flashes in subfunction mode. (p.51)
Lights up when the alarm function is on. (p.35)
Lights up when the filter function is on. (p.34)
®
Lights up when the Bluetooth
function is on. Flashes when
data is being sent or received. (model FT6381 only) (p.42)
Lights up when the auto-power-save function is on. (p.53)
Indicates the remaining battery power. (p.22)
Lights up in AC current measurement mode. (p.29)
Lights up in resistance measurement mode. (p.26)
Lights up in resistance measurement mode when a current
that could affect the measured value is detected. (p.28)
Lights up in resistance measurement mode when the mea-
sured ground loop has a high reactance component or capac-
itance component (
45
or greater). (When the [
] mark
±
°
lights up due to a low measured resistance value, it is likely
that the displayed value indicates a shorted measurement
loop rather than normal grounding resistance. When the
]
[
mark lights up, the loop may have a break in it. In this
case, the mark indicates that the wires have been coupled by
capacitance.) (p.28)
Lights up during internal memory operations. (p.38)
The number of measurement data points stored in memory is
shown to the right.
