3.1.6 Measurement level
ET35’s measuring signal level will be set according to the effective value of the
measuring sine wave signal. The frequency of the sine wave signal is the measureing
frequency, generated by the instrument internal oscillator. Users can either set the
oscillator voltage level or the oscillator current level. Output impedance is adjustable.
Note: The measuring current of the ET35 is set as the output current value when the
measured component is short circuited and the measured voltage is set to the output
voltage values when the measured component is open circuited.
The automatic level control function of ET35 may achieve constant voltage or current
measurements. You can then set the automatic level control function (constant level field)
on in the page of measurement setup. When the constant voltage level or constant current
level measurement is conducted, a "*" sign will appear after the current level value.
ET35 has two ways to set the measurement signal level. One is to use the function
keys, and the other is to use the numeric input key. The voltage level can be set within the
range of 10mV ~ 2V, and the current level within the range of 100uA ~ 20mA.
The measurement level can be set in the pages of component measurement and
measurement setup.
The steps of setting the measurement level:
1. Press the [Meas Setup] key.
2. Use the arrow key to select "level", and press the [Enter] key.
3. Use the function keys or numeric keys to enter the measurement level. When the
data are entered using the numeric input key, the function key will change to the unit (mV,
V, uA, mA). You can use these function keys to enter the unit. When using the [Enter] key
to enter the level, the default unit of level is mV.
Note: you must use the numeric input key and unit function key to switch the
measurement level between current and voltage.
