5.5. Frequency output
The flowmeter is provided with a frequency output transmitter function. The high or
low frequency output displayed indicates the high or low flow rate reading. The
user can reset the frequency output as well as flow rate as his requirements.
For example: if a pipe flow range is 0~3000m3/h, the relative frequency output
required is 0~5000Hz, and the configuration is as follows:
In Window M68 (low limit frequency output flow value), input 0;
In Window M69 (high limit frequency output flow value), input 3000; Typical OCT

5.6. 4~20mA current loop output verification (optional)
Processing a current loop output exceeding an accuracy of 0.1%, the flowmeter is
programmable and configurable with multiple output modes such as flow rate or
fluid velocity. Select in Window M55. For details, please refer to "Windows Display
Explanations".
In Window M56, enter a 4mA flow rate or fluid velocity value. Enter the 20mA flow
rate or fluid velocity value in Window M57. For example, if the flow range in a
