Note: After bias current isolation function is turned on, the test accuracy will  be influenced, so under the 
condition of low frequency and bias current, the bias current isolation function should be set as OFF. 
Setting the Bias Current Isolation Function  
Follow these steps and set the bias current isolation function ON or OFF. 
1.  In the <MEASURE SETUP> page, using the cursor keys, move the cursor to the ISO zone, 
the following soft keys will be displayed: 
2.  Move the cursor to ISO zone, the following soft keys will be displayed: 
  ON: Press this soft button to turn on the bias current isolation function. 
  OFF: Press this soft button to turn off the bias current isolation function. 
Average (AVG) 
The Average sets the number of samples to use for averaging before a measurement is made.  
This can be set from 1 to 255. The higher the number of samples used for averaging, the higher 
the accuracy of the measurement. The lesser the number of samples used for averaging, the 
lesser the accuracy of the measurement; but measurement speed will increase. 
Setting Test Average 
1)  In the  <MEASURE  SETUP> page, using the  cursor  keys,  move the cursor to  AVG, and 
the following softkeys will be displayed: 
  INCR +  This key is used to increase the number of measurements used to average 
the final value displayed. 
  DECR - This key is used to increase the number of measurements used to average 
the final value displayed. 
2)  Use INCR + or DECR – softkeys or the numeric keypad, following by Enter, to set the 
average amount. 
Level Monitor (Vm/Im) 
The level monitor function can monitor the actual voltage or current across the DUT.  
The monitored value is displayed on the <MEASURE DISP> page as: 
  Vm: Monitored voltage 
  Im: Monitored current
