YEW CA13

Pulse generator and meter:
Wide setting range of 0.1 Hz to 11k Hz. A simple key action switched over the function between a pulse generator and pulse meter, suitable for checking flowmeters and receiver instruments.

Both voltage pulses and contact pulses are available:
The CA13 can generate and measure both voltage pulses (amplitude of +0.1 to +15V, zero-based waveform) and contact pulses.

Duty ratio setting key:
The duty ratio of the generated pulses can be set in increments of 10% (Within the range of 10 to 90% except for the two-phase output).

Display switching key:
Switches over the display between the frequency setting, amplitude setting and number-of-pulse setting (when using a PULSE CYCLES range).

Plug for input and two-phase output:
The leftmost input plug can be used as an additional output terminal only by setting an internal dip switch for two-phase output.

Generation of DC voltage and current:
A DC voltage (0.1 to 15V) and current (step setting of 4↔8↔12↔16↔20 mA) can be generated. (Note that the accuracy is ±0.5% of full scale. Use this function only for simplified checks. For precise measurement, use the CA11.)

Pulse cycle output:
A set number of pulses (of a desired frequency and amplitude) can be output, ideal for checking totalizer counters.

CPM function:
The CA13 can count the number of pulses per minute when using the measurement function, suitable for totalizing the flow rate based on discontinuous pulses from a flowmeter. When using the generation function, the pulse train signal to be output can be set by a number of pulses per minute (60 CPM=1 Hz).
