Key Advantages of TD1870 Multifunction Calibrator

1. Wide Range & High Accuracy

The output range of TD1870 multifunction calibrator fully covers the working span of most handheld and benchtop electrical instruments. With DC voltage stability up to 5 ppm/24h, it ensures consistent and precise output across long calibration cycles.

2. Advanced Simulated Resistance

Features both 2-terminal and 4-terminal simulated resistance output. Especially for low-resistance calibration, the 4-wire configuration eliminates lead resistance errors, offering:

• Finer and more sensitive adjustments

• Lighter and more compact setup compared to traditional resistance boxes

• No mechanical switching errors or residual resistance interference

3. Smart Protection Mechanism

To safeguard internal components, TD1870 multifunction calibrator includes a built-in safety circuit protection system. In the event of an incorrect external input, the system will automatically trigger an alert and display a warning on the screen. Once the issue is resolved, users can easily reset the system with a single touch—minimizing downtime and repair costs.

4. User-Centered Design

TD1870 multifunction calibrator is built for efficient operation and intuitive control:

• Large full-color touchscreen with high brightness and touch support
  

• Digital programmable buttons for step, fixed-point, and rotary adjustments
  

• Front panel wiring layout for fast connection changes
  

• Solution value mode for streamlined operation in varied test scenarios
  

Whether you are performing routine calibration, developing new electrical instruments, or maintaining test equipment, TD1870 muitifunction caibrator delivers the precision, reliability, and ease of use that modern professionals demand.
