5. Characteristics of TD1860 Multifunction Calibrator

☆Wide output range

TD1860 Multifunction multiproduct Calibrator

Solution value: The multifunctional standard source output range of TD1860 covers the working range of electrical measuring instruments such as 4.5-digit and below digital multimeters, and can be calibrated directly using the standard source method.

☆High stability and accuracy

The DC voltage stability is up to 0.005%/24h, and the DC current stability is up to 0.01%/24h.

☆ High load capacity

TD1860 Multi function multiproduct Calibrator

The voltage and current standard sources of TD1860 have strong driving capabilities, ensuring that the instrument can still maintain high-precision and high-stability constant voltage or constant current output when connected to a large load, and can cover the calibration of analog pointer instruments.
Strong output load capacity can also achieve simultaneous calibration of multiple digital AC and DC instruments.
(Note: The specific number is related to the load size of the meter being tested)

☆ 4-terminals Simulated DC resistance

2-terminals and 4-terminals resistance wiring mode. When calibrating the low value resistance, the four wire system wiring mode can effectively eliminate the measurement error caused by the resistance of the test lead and improve the measurement accuracy.
Compared with the standard physical resistance box, the analog resistance output has the following characteristics:

☑ Continuously adjustable, with better adjustment fineness and sensitivity

☑ Smaller size and lighter weight

☑No influence of transfer switch error, residual resistance error and contact resistance error.

☆ Safety protection function

TD1860 Multi function multiproduct Calibrator

Accidental voltage or current applied to the output of the multifunction calibrator may cause serious damage to the built-in components of the instrument, resulting in expensive repair costs and a decrease in the use rate of the instrument during the repair period.
TD1860 has a complete safety circuit protection function. When the self-protection is triggered, the device will alarm and pop up an alarm prompt on the screen interface. After the user checks and confirms and eliminates the fault, it only takes one button to reset the protection to return to normal.

☆ Easy to operate

TD1860 Multi function multiproduct Calibrator

Large-size touch screen: full color, high screen brightness, clear picture quality, support touch operation, comprehensive functions, simple and fast.
Digital programmable buttons: can realize multiple input methods such as fixed-point output, rotary encoder, and step adjustment, and the operation is convenient and fast.
Front panel wiring: convenient for users to replace current and voltage test wires when checking the meter.
Solution value: This combined operation method effectively improves the convenience of operation to adapt to a variety of application scenarios.

☆ Multiple output\adjustment methods

The instrument has a "Direct Output" mode. You can directly set the required output value by pressing the digital buttons on the console or clicking the touch screen. The instrument will automatically switch to the optimal range output, making it very convenient to calibrate digital instruments.
Especially when setting the AC power output, you can directly input the voltage and current amplitude, frequency and phase angle at the same time (as shown in Figure b above), which is very convenient to use.

Calibration of the analog pointer meter usually needs to test scale by scale, especially "differences between rising and falling" (the change caused by the rise and fall of the calibration point).
It is relatively inconvenient to use digital fixed-point output to adjust the output of the standard source to align the scale. For this reason, we provide users with a remote box (optional accessory). Through coarse adjustment and fine adjustment operations, the output can be quickly adjusted to align with the scale of the meter being tested, which is very convenient for completing the calibration of analog meters. This function is especially useful when friction or hysteresis effects need to be considered during movement.

☆Multiple output & adjustment methods

When calibrating an electrical measuring instrument, it is usually necessary to select calibration points in proportion to the range of the instrument being tested.
Users can easily select calibration points for the instrument being tested through the percentage "calibration point" function on the touch screen of this instrument.

The instrument is equipped with a "Rotary Knob" on the front panel. Click the left and right arrow keys to adjust the cursor position, and then rotate clockwise or counterclockwise to increase or decrease the output value.

☆Multiple output & adjustment methods

Use the key ↑10%, ↓10%, ×10, ÷10 on the front panel, can realize the adjustment of the quantity value, and can also be used to perform the relevant test of linearity.

☆ Dedicated test software (option)

TD1860 Multi function multiproduct Calibrator

Optional dedicated calibration software, refer to the test items in JJF 1587-2016, JJG 124-2005 and other regulations and specifications, the software protocol library is suitable for various specifications of the tested instruments, supports fully automatic or semi-automatic calibration of the tested equipment, raw data recording, analysis, management and customized template report export. Compared with traditional manual calibration, it has obvious advantages, effectively solves various inconveniences of manual calibration, and significantly improves work efficiency.
(Note: During fully automatic calibration, the tested equipment should have communication functions and open communication protocols to enable data reading)
The software functions can be customized according to customer needs, and support subsequent software upgrades to add new procedure test requirements.
