Controller Button Instructions

1. Select a setting: Press the Mode button to display the arrow indicator. Move the arrow to the item you want to adjust.
2. Adjust speed or time: When the arrow points to one of the first five settings, press Increase (+) or Decrease (-) to adjust the speed integer value, speed decimal value, or time value.
3. Save settings: When the arrow points to Save, the sixth item, press the Save button to store the parameters for future operation.
4. Run the pump: When the arrow points to RUN, the seventh item, press Auto Forward or Auto Reverse to operate automatically at the preset speed and time. Use Manual Forward or Manual Reverse for manual movement; release the manual button to stop.

Technical Specifications

QHZS-001A Communication Commands

The pump supports direct USB communication and UART serial communication at 9600 baud. With a suitable external UART converter, the host controller can communicate through RS232, RS485, or CAN. These converted interfaces require separate conversion hardware and are not built-in ports.

A computer or host controller can send the following commands to set operating values and control pump movement. In each command, xx is the value to be set; use the valid parameter range shown in the product specifications.

UART Connection Note

Communication control requires a buyer-supplied connection tool; a CH340G module is generally recommended. Supplier diagrams show conflicting TX/RX wiring conventions, so verify the labels and signal direction on the supplied controller and converter before connecting. Do not rely on wire color or an unverified pin-to-pin assumption.

Dimensions

Operating Controls and Timer

• The foot pedal can replace the panel button for frequent start and stop operation.
• Speed settings support two decimal places within the model's stated 0.01-150 mm/min travel-speed range.
• Run duration can be set in hours, minutes, and seconds. The pump stops automatically when the configured time ends.

Typical Laboratory and Process Applications

The QHZS-001A can be used for controlled laboratory animal injection setups, nanomaterial experiments, wet spinning, electrospinning, cell-culture liquid handling, microfluidic control, industrial process trials, liquid sampling, and dispensing when the selected syringe, tubing, flow requirements, and operating setup are compatible.

Frequently Asked Questions

Can this laboratory syringe pump perform both infusion and withdrawal?

Yes. The QHZS-001A supports forward infusion and reverse withdrawal through manual or automatic operation.

Can the pump be started and stopped without using the panel buttons?

Yes. The included foot pedal provides hands-free syringe pump start and stop control for repeated laboratory or process work.

What is the adjustable travel-speed range?

The syringe pump travel speed is adjustable from 0.01 to 150 mm/min.

What is the maximum mechanical travel?

The QHZS-001A has 140 mm travel. Select the syringe and operating setup so the required plunger movement remains within this range.

What power supply is included?

The A2 package includes a 12V / 3A power adapter, controller, foot pedal, and pump. The syringe is not included.
