DM9648-F digital electric frequency meter
1-Function :
Mainly used in the measurement and digital indication on frequency value in an electric circuit. Switching value
output (higher and lower limit alarms) modules, analog value transmitting output module, RS485 communication
module are optional offered . It can conveniently realize the setting of many parameters including higher and lower
limit alarm value,alarm return difference, communication address and communication baud rate, transmitting output
specification, transmitting output range by the keyboard of instrument.
