Operating Facilities
Noise Filter
The Filter key controls a low pass filter, with a cut-off frequency of about 50kHz, to assist in
obtaining stable readings at low frequencies.
Hold
Pressing the Hold key will hold the current measured value in the display, with the Hold indicator
on, until the Hold key is pressed again. The measurement continues in the background when
Hold is on. A long press on the Hold key clears old data and restarts the measurement.
Intelligent Power Switching
The unit automatically selects the best available power source of AC adaptor, USB or battery.
Intelligent switching avoids discharging the battery overnight when operated from externally
switched AC power.
A press-to-measure facility allows a quick measurement to be made by pressing a function select
key which will power the instrument up in the corresponding function. The instrument will
automatically switch off 15 seconds after the last key-press.
Remote Control
All capabilities can be controlled remotely and measurements read through a USB port.
The instrument can be powered (but the battery cannot be charged) by the USB host.
