Keypad Operation
The operation of the HI-4416 System Readout is
controlled by membrane switches. To activate a
switch, press gently on the center of the pad with
your fingertip. Do not use hard or pointed objects.
On/Off —The On/Off keypad activates the readout.
At power-up, a self-test procedure is automatically performed. As part of this
procedure, all segments of the LCD will activate for two seconds, then the
version of software installed in the HI-4416 will appear, followed by the current
range of the probe connected to the readout. The System Readout then switches
to normal (measurement) operation. The HI-4416 does not require any warm-up
or settling time prior to use. Pressing On/Off again turns the readout off.
