Description
The F Series Digital Switchboard Monitor is a bright, easy-
to-read device that’s perfect for Utility, Industrial and Power
Generation Applications. It can display any AC or DC value,
and has a 0-1 or 4-20mA Input for Process and Transducer
Signals.
Superior Accuracy
The unit’s 12-bit Analog-to-Digital Converter provides
superb accuracy throughout the scale. This eliminates
the chronic problem analog meters have at the low end.
Resolution is often critical with a lightly loaded panel; this full
4-digit monitor has a resolution to 9999 counts.
Super-Large LED Display
The super-large, bright LED display can be read up to 300
feet away. This reduces user error and eliminates eyestrai

meters.
Rugged, Industrial Design
The top-quality LED Display, heavy-duty metal enclosure
and electrically protected power supply make this a device
that will operate reliably for many years.
Highly Accurate Frequency Measurement
The FF60-1000 models accurately measure Frequency
using a Crystal Oscillator and a unique Phase Lock Loop
scheme. This technique allows the unit to be calibration free.
It also allows the monitor to reject noi
