How to Use Digital Ultrasonic Cleaner | Operation Guide for KHTD Series Degas Ultrasonic Cleaner
How to use a digital ultrasonic cleaner for professional results? If you have recently invested in a KHTD Series digital ultrasonic cleaner, such as the one featured below, this comprehensive guide will walk you through the proper operation to ensure optimal cleaning performance and equipment longevity. These high-performance machines utilize advanced ultrasonic cavitation technology—creating millions of microscopic bubbles that reach into the smallest crevices to remove dirt, grease, and oxidation from delicate items without causing damage.
Applicable Models
This operational guide is specifically designed for all digital heated ultrasonic cleaners within the KHTD series, which are widely utilized across the jewelry, dental, automotive, and electronics industries for their precision and reliability. The instructions provided here apply to the following range of models: K113HTD, K120HTD, K230HTD, K340HTD, K360HTD, K410HTD, K615HTD, K320HTD, K820HTD, and K1030HTD. Whether you are operating a compact unit for intricate watch parts or a high-capacity industrial model, the intuitive digital interface allows for exact time and temperature adjustments to ensure a perfect clean every time.
Preparation
- Fill the stainless steel tank with your cleaning solution. Use water or a water-based cleaning solution suitable for your items. Never run the machine with an empty tank.
- Plug the power lead into a grounded electrical outlet.
- Power on the unit. The LED display will show the current ambient temperature and a default timer reading of 0 minutes.
Getting Started
Here is the KHTD series digital ultrasonic cleaner operation panel, showing all the buttons and the LED display.
The basic operations include: Timer settings, Temperature settings, and the degassing function. Below are the detailed steps showing how to use a digital ultrasonic cleaner.
Timer Settings
The digital timer controls how long the ultrasonic cleaning cycle runs.
- Press the time ▲ button once to add 1 minute. Press and hold to increase the time continuously.
- Press the time ▼ button once to subtract 1 minute. Press and hold to decrease the time continuously.
- The ultrasonic cleaning stops automatically when the timer reaches 0.
Set your working time based on the condition of your items. Lightly oiled objects may need only 3 to 5 minutes. Heavily oiled parts may require 15 to 30 minutes or longer.
Temperature Settings
Heated solutions enhance cleaning effectiveness. For most applications, a working temperature range of 40°C to 60°C is optimal. As a digital heated ultrasonic cleaner, it’s easy to adjust the temperature settings as needed.
- Press the temperature ▲ button once to raise the target temperature by 1°C. Press and hold to increase continuously.
- Press the temperature ▼ button once to lower the target temperature by 1°C. Press and hold to decrease continuously.
- The LED display shows both the set temperature and the actual solution temperature separately, so you can monitor the heating progress at a glance.
Important: The heater only works when the set temperature is higher than the current actual temperature. When the solution reaches the set temperature, the heater indicator light turns off automatically. The ultrasonic function can run with or without heating—you control each independently.
Ultrasonic Cleaning and Degas Mode
The control panel has two ON/OFF keys:
- Right ON/OFF key — Controls ultrasonic cleaning and degas function.
- Left ON/OFF key — Controls the heater.
Press the right ON/OFF key to start ultrasonic cleaning. Press it again to stop.
How to Activate Degas Mode
Freshly poured cleaning solution contains microscopic air bubbles that weaken cavitation. Degas mode removes these bubbles so your cleaning cycle runs at full strength.
- Press and hold the right ON/OFF key for 5 seconds until you hear a beep. The machine is now in degas mode.
- To return to normal ultrasonic cleaning mode, press and hold the right ON/OFF key again for 5 seconds until it beeps.
Run degas mode whenever you fill the tank with fresh solution, before placing your items in the bath.
After Cleaning
- Allow the solution to cool. Do not pour hot water out immediately. Hot water can cause burns and may damage internal machine components.
- Empty the tank.
- Wipe both the inside and outside of the cleaner with a clean, dry cloth. This prevents residue buildup and keeps the machine ready for the next use.

Frequently Asked Questions
Q: How do I know when the degas mode is running?
When you press and hold the ultrasonic ON/OFF key for 5 seconds, a beep confirms that degas mode is active. The machine runs a pulsed on/off cycle during degassing rather than continuous ultrasonics. Press and hold again for 5 seconds to switch back to normal mode.
Q: Can I run the heater and ultrasonics at the same time?
Yes. The heater and ultrasonic functions operate independently. You can heat the solution first, then start ultrasonics, or run both together for warm cleaning cycles.
Q: Why does the heater indicator light turn off during a cycle?
This is normal. The light goes out when the solution reaches the set temperature. If the temperature drops during cleaning, the heater will cycle back on, and the indicator will light up again.
