GENERAL ORDERING INFORMATION:
Specify Meter Color & Digit Size, Meter Power and a Signal Conditioner from the list below. Specify Analog Output, Setpoint Output and Digital Interface if needed. These meters are shipped with a standard configuration and range shown below for each signal conditioner and output option type. All information for making changes is covered in the supplied Owners Manual. For other scalings or configurations, add the SC (Special Configuration) option.
DESCRIPTIONS:
Duty cycle is a measure of ON or OFF period as a percentage of total period. Duty cycle is determined by averaging an integral number of periods over a gate time which is selectable from 10 ms to 199.99 s. The same signal is applied to Channels A and B. The meter divides the average pulse width by the period between pulses and expresses this ratio in percent. A resolution of 1%, 0.1% or 0.01% is selectable. By selecting leading or falling pulse edges, the ON or OFF duty cycle can be displayed.
Duty cycle measurement is used to monitor modulated proportional control systems and pulse-modulated systems, such as radar, lasers or packet radio. For long periods, duty cycle can be measured by using the A and B channels of the Micro dual-channel counter to totalize AC line cycles and having the counter display the ratio of the two totals scaled to percent.
The Micro duty cycle meter uses the FR dual-channel signal conditioner board and Extended counter main board.

The Micro duty cycle meter uses the FR dual-channel signal conditioner board and Extended counter main board.
The dual-channel signal conditioner accepts inputs from proximity switches with PNP or NPN output, TTL or CMOS logic, magnetic pickups, contact closures, and AC signals from 12 mV to 250 Vac. Jumper selections provide optimum operation for different sensor types and noise conditions.
A built-in isolated 5, 10, or 24 Vdc excitation supply can power proximity switches and other sensors, and eliminate the need for an external power supply.
Plug-in isolated analog output, dual setpoint controller, and RS232/485 serial communications boards can upgrade Micro and Mighty Series duty cycle meters from a stand-alone monitor to system interface and control. The ability of the meter to output an isolated 0-10 V or 4-20 mA analog signal turns into an analog transmitter.
Micro Series meters can be powered from 95-240 Vac ±10% and 95-370 Vdc, or optionally from 12-34 Vac and 10-48 Vdc. Any setup functions and front panel keys may be locked out for simplified usage and security. The popular 1/8 DIN version with 0.56″ high digits is environmentally sealed to NEMA-4X (IP65) from the front when panel mounted, and is available with red or green LEDs.
