JCBC-1002 Standard Frequency Signal Generator and Frequency Measurement Instrument is a device that can send pulses in the frequency range of 1~9999 or 0.3~999.9 or 0.24~99.99 or 0.240~9.999Hz, and has multiple functions such as continuous sending, single sending, measurement and sending
The JCBC-1002 is a standard frequency signal generator that can output pulse signals from 1 Hz to 9 999 Hz. It offers automatic shutdown after 1‑255 minutes of inactivity, adjustable pulse amplitude via an external voltage source, and high accuracy of 0.001 % + (output) × 0.000019 %.
The instrument provides a dual‑digit display: the lower segment shows the output frequency, while the upper segment shows either the process value in continuous mode or the number of pulses in single‑send mode. Users can switch between continuous and single‑send modes by setting the B‑menu out parameter, and adjust frequency using the A/M and decrement keys with visual feedback from the B indicator lamp. Signal wiring includes dedicated connectors for ground, frequency output, and external voltage adjustment. This manual is written in Chinese.
| Frequency range | 1 ~ 9999 Hz |
|---|---|
| Auto‑shutdown timer | 1 ~ 255 minutes |
| Accuracy | 0.001 % + (output) × 0.000019 % |
| Pulse amplitude adjustment | via external voltage source |
| Signal connector colors | Yellow = frequency output (+), Red = external voltage adjustment |
The device can generate pulse signals from 1 Hz up to 9 999 Hz.
Set the OFF‑time parameter to a value between 1 and 255 minutes.
Connect an external voltage source to the red connector to adjust the pulse amplitude.
Set the B‑menu out parameter’s units digit to 0 for continuous mode or 1 for single‑send mode.
