3 Menus
The MENUs consists of ten parts: [INPUT/FILTERS], [REF/PHASE], [GAIN/TC], [DISPLAY], [SAVE/LOAD],
[CHANNEL OUTPUT], [SAMPLE], [AUX OUTPUT], [SYSTEM] and [AUTO SET]. Press one button and then
the interface will switch to the corresponding sub menu display.
3.1 [INPUT/FILTERS]
You can enter this submenu by choosing the [INPUT/FILTERS] in menus of front panel, as is shown in Fig.16..
Fig.16 [INPUT/ FILTERS] submenu
3.1.1 <Source>: Setting the Input Signal Mode
<A>
Single-ended voltage input mode.
<A-B>
Differential voltage input mode.
<I>
Current input mode.
Note that when choose mode <A> and mode <A-B>, the amplitude of the input signal must be less than 1Vrms.
3.1.2 < Current Gain >: Setting the Current Gain
<1M>
The input current is amplified by the gain of 10
6
V/A.
<100M> The input current is amplified by the gain of 10
8
V/A.
3.1.3 < Grounding >: Setting the Ground Mode
<Float>
The shields of the input connectors are connected by 10 kΩ to the chassis ground.
<Ground> The shields are connected by 10 Ω to ground (connected to the earth).
In general, if the current of the input signal is not large, it can be ground and short the signal ground and system.
This method can avoid signal drift caused by the float signal ground. When there is large potential difference
