Switching displays
Analog and logic/pulse can be switched as shown below.
• Display Logic/Pulse Data
Analog settings
Specifies the conditions for analog signals.
When you use CH ALL to set an input, range and filter, all channels are set to the same values if the input
is the same. Range is set only for the same input channels. However, the range of a channel is not changed
if its EU (scaling) is set to On.
Span All Settings is set only for the same range channels.
* If the first channel in a channel group (CH1 if CHs 1 to 10 are displayed) has an input that is set to Off, the
input of CH ALL is set to Off.
(1)-1 Input
This is used to select input condition

(1)-2 Sensor
This is used to select the thermocouple connected when the temperature is input and type of resistance
bulb. Additionally, perform the settings for sensor operation when connecting the optional GS sensor or
terminal/addapter. For details, refer to " ***** setting".
* The ***** symbols indicate the abbreviation of name (model).
(1)-3 Range
This is used to select the range of measurement.

* Please select each GS sensor and terminal/addapter in reference to " ***** setting" described below.
* The ***** symbols indicate the abbreviation of name (model).
3-24
Input signal measurement is disabled. No waveform or digital value is displayed.
Used for measuring direct-current voltage.
Used for measuring temperature.
Used for measuring humidity with the humidity sensor B-530.
In this case, the voltage range will become 1 V, and the EU settings will not be available.
20, 50, 100, 200, 500 mV; 1, 2, 5, 10, 20, 50, 100V 1-5 V
2000, 500, 100℃
* This setting is used for only standard terminal, Withstand high-voltage high-precision terminal. The
resolution varies depending on the range.
