Capacitors have been incorporated into the input circuit to increase the noise-elimination capability.
After voltage measurement, when the inputs have been disconnected, there will still be some electric charge remaining.
Before starting another measurement operation, short-circuit the + and – terminals to enable self-discharge.
The GL860 has a scan system.
While in the status (open) in which signals are not input to the input terminal, measured results may be influenced by
signals from other channels. In such a case, turn OFF the input setting or short circuit +/–.
If signals are input correctly, measured results are not influenced by other channels.
CAUTION
