Absolute error of my measurement

"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.

Operation instructions

  1. Press the power on/off button to turn power on. 
  2. Adjust the voltage knob to set the desired voltage. (Voltage level is shown on the digital display). 
  3. Adjust the current level pot with a small regular screwdriver to set the (maximum) desired current level. (The current of the power supply is set to be the maximum at the factory). 
  4. Connecting a load to the output terminals and pressing the output switch will illuminate the output indicator light and the current output can be read on the digital display.

Power supply to load four-wire connection method

The sampling terminals are used under the following conditions: if the load has a distance from the power supply, the sampling terminals may be used to compensate for the inherent when using voltage drop a longer power line.

Sampling terminals connection to compensate the voltage drop:
