Basic operation of U2815 LCR meter
Basic operation of U2815 is as follows:
Use menu keys ([MEAS DISP], [MEAS SETUP], [SYSTEM]) and soft keys to select the desired page.
Use cursor keys ([←][→]) to move the cursor to the desired zone. When the cursor moves to a specified zone, the zone will become reverse expression.
The soft key functions corresponding to the current zone of the cursor will be displayed in the soft key zone. Users can select and use the desired key. Numeric keys, [BACKSPACE] and [ENTER] are used to input data. When a numeric key is pressed down, the usable unit soft key will be displayed in the soft key zone. You can choose a unit soft key or press [ENTER] to end data inputting. When [ENTER] is used to terminate data inputting, the unit of data will be set to a default unit, such as Hz, V or A. For example the default unit for frequency is Hz.

How can be measurement frequency set in U2815 LCR meter?
U2815 LCR meter provides two methods to set measurement frequency. The first one is to use soft keys and the other one is to input data by using numeric keys.
1) Move the cursor to the FREQ zone, the following soft keys will be displayed.
INCR++
This is a coarse adjustment soft key used to increase the frequency. Press this key, the frequency will change as the following sequence: 20Hz, 100Hz, 1kHz, 10kHz, 100kHz, 200kHz.
INCR+
This is a fine adjustment soft key used to increase the frequency. Press this key, the frequency will switch.
DECR-
This is a fine adjustment soft key used to decrease the frequency. The selectable frequencies are the same as that of INCR+.
DECR--
This is a coarse adjustment soft key used to decrease the frequency. The selectable frequencies are the same as that of INCR++.
2) Use soft keys or numeric keys to select or set frequency. When using numeric keys to input the required frequency value, the soft key displays the available frequency units (Hz, kHz and MHz). You can use unit soft key to input unit and data. When using [ENTER] to input frequency, the default unit is Hz.
