SIT-12 Smart Injector Tester

The SIT-12 Tester is a portable device for measuring electrical parameters of (unit) injectors. Thanks to the unique combination of all the electrical measurements into one device it is possible to quickly diagnose faults.

Low resistance measurements with miliohm resolution and the function to determine the inductance allow for checking injector coils. Thanks to the capacitance and resistance measurement it is possible to check piezo stacks. For each kind of injector – no matter whether solenoid or piezo – it is possible to perform high voltage insulation measurement. Maximum voltage is 500V.

SIT-12

  1. Will the SIT-12 device measure the resistance of the piezoelectric stack of the injector?

The SIT-12 tester measures resistance in two ranges. The higher one, ranging from 8kΩ to 1050kΩ, is intended for the measurement of the piezoelectric stack.

  1. Is the piezo stack resistance measured under high voltage in the SIT-12 device? Is it possible to regulate the voltage?

Piezoelectric stack resistance is measured with low voltage, below 5V that cannot be changed. The test voltage is only selected in the insulation test. However, this measurement is intended for ranges well in excess of the piezo resistance (typically 150 – 250kΩ).

  1. Can capacitance measurements taken with a different meter give a different indication?

The capacity of the piezo injector is not a “pure” capacity, therefore the measurements made with different instruments (methods) may give different results, or even no result. The principle of measuring capacity based on the charging time from a current source used in the SIT-12 is a universal method and widely used in laboratory bench multimeters.

  1. Can the data on the injector coil inductance be helpful in assessing the condition of the injector?

The data provided by various programs and manufacturers relates to their own test devices. In the case of inductance, despite giving the same result units (μH or mH), you must take measurement conditions into account. SIT-12 measures inductance at two frequencies. They are higher than those used usually by other manufacturers. Therefore, the results cannot be compared directly.

  1. The display contrast is low when the device is turned on.

Until the display of the logo is complete, the display may not have the optimal contrast. Only after switching to the menu list, the display has a stabilized contrast to the operating conditions (ambient temperature). The device does not have a contrast correction menu due to the built-in automatic contrast adjustment depending on the temperature.
