4. Screen Description
Most of data above the white line are measured values:
<+0.0000 >: the current measured value, display 4 digits, 1 sign bit, 1 decimal bit.
<mVs>: unit of measured value, it can be set by the 鈥?em>Unit鈥?/em> key.
<R>: R means that it鈥檚 in the remote control mode at the moment, without it means local control mode; in a remote control mode, only 鈥?em>Local鈥?nbsp;key is valid in the keyboard, other keys are locked.
<2013-7-6 10:7:42> is the current system time.
<PH:+0.0000>: at the peak hold mode, value displayed, means it is the positive peak value.
<PL:+0.0000>: at the peak hold mode, value displayed, means it is the negative peak value.
<PP:+0.0000>: the absolute value of the peak value.
