"Absolute measurement error" service allows you to estimate the measurement accuracy considering uncertainty (error) in the absolute value. It's important if you take measurements at the range edge when the error value contributes to the value displayed on the device screen.
To get the value range it'd be enough to enter the estimate of the value under measurement into Value input field and to see the range of possible values taking all of the standardized errors into consideration.
Note: a point is used as a separator of the integer and fractional part.
When I press “Remote” there is nothing happening to AKTAKOM APS-7306 power supply control. What is the reason?
In order to ensure the safe operation of AKTAKOM APS-7306 power supply and the connected equipment the command to turn off the remote mode in the program does not work. To switch to local control turn the power off and then on again.
What current protection do AKTAKOM power supplies use?
AKTAKOM power supplies use 2 types of protection.
In low end power supplies the current protection is provided mostly by "current stabilization" (CC) mode. When the load resistance decreases (or short circuit) the power supply reduces the output terminals voltage to the minimum level and remains in this condition until the load resistance appears on the terminals. When resistance appears, voltage (and current) will increase proportionally to the set value.
High end power supplies have also over current protection mode (or OCP mode) in addition to the current stabilization mode. OCP mode is activated regardless of current stabilization mode and allows you to set any current limit value at which the power supply will turn off the output terminals voltage. After the protection is activated the power supply terminals will stay off until some certain buttons on the device control panel are pressed, regardless of the load state.
Multi-channel power supplies use OCP options both for separate channels and for the total output current of the power supply.
Thus we may assume that devices without OCP mode use current stabilization mode for the current protection. In devices equipped with OCP mode the current protection works in the trigger mode.
However it should be noted that in both cases, when the protection is activated, the output terminals (and the load) are not galvanically isolated from the power supply.
May I use AKTAKOM power supplies to charge accumulators?
AKTAKOM power supplies can’t be used for accumulator charging since it may cause the accumulator breakage (recharge, electrolyte boiling, extra pressure of the internal gas which will lead to the accumulator explosion). Accumulators should be charged with the current source which controls the accumulator voltage and regulates the charging current accordingly. When the required accumulator voltage is achieved such type of source simply stops the charging process, its name is a charging device.
