SIGNAL GENERATOR: Internal protection against inversions and overcurrents, protection voltage of 30V. A single 3.7V lithium integrated power supply; the duration of use varies according to the use [it can last more than 6 hours with a continuous output of 20 mA]. With the internal battery voltage indicator [UV light] when the under voltage light is on, please stop charging.

AUTO OUTPUT FUNCTION: This function can automatically change the output mode according to the program. It can only be output automatically by setting the parameters used for aging and automatic testing of valves and other equipment.

THIS FUNCTION INCLUDES THE FOLLOWING: Auto mode, cycle number, initial value, incremental value, decrement value, incremental duration, decrement duration, start point delay, endpoint delay, and end value. For the active current, the passive current and the voltage output, there are separate adjustment parameters to facilitate the adjustment of various output signals.

VC CONVERSION FUNCTION: This function is mainly used for some temporary voltage and current conversions, such as converting a 0-10V input to a 4-20mA output. VC Active Conversion: converts the input of the voltage signal into an active current signal output. Passive VC conversion: converts the input of the voltage signal into a passive current signal output.
