7. Adjustment
Performs the output zero and span adjustments.
For this instrument, the output adjustment has already been completed when shipped.
If the instrument is used with the ordered Input/Output spec, the adjustment is not required.
However, for calibration, or for the fine adjustment of the SGD to which any equipment is
connected, perform the adjustment.

Connect an mV generator or Dial resistor to the input terminals of this instrument.

Connect a digital multimeter to the output terminals.

7.1 Basic Operation of Adjustment

For adjustment, use the following trimmers on the front panel.
Output 1 Zero: Adjusts the value of Output 1 Zero.
Output 1 Span: Adjusts the value of Output 1 Span.
Output 2 Zero: Adjusts the value of Output 2 Zero. (only for SGDW)
Output 2 Span: Adjusts the value of Output 2 Span. (only for SGDW)

7.2 Adjustment
All adjustment items are shown below.
Perform adjustment as follows.
7.2.1 Output Adjustment
The following outlines the procedure for Output 1 adjustment.
① Enter the value corresponding to 0% output, and adjust the value using the
‘Output 1 Zero’ trimmer while viewing the output value (on the digital multimeter).
② Enter the value corresponding to 100% output, and adjust the value using the
‘Output 1 Span’ trimmer while viewing the output value (on the digital multimeter).
③ Enter the value corresponding to 0% output again, and confirm the output value
(on the digital multimeter).
④ If the value corresponding to 0% output is not at 0%, repeat steps ① to ③
again.
7.2.2 Output 2 Adjustment
The procedure for Output 2 adjustment is the same as that of Output 1 adjustment.
Use Output 2 Zero and Span trimmers for adjustment.

8. Operation
8.1 Indication after Power-on
After the power is turned on, the instrument is switched to warm-up status for 3
seconds. Multi-Display A indicates a model name, and Multi-Display B indicates the
input code and output code.
(e.g.) SGD-A01-0-0
Multi-Display A:
Multi-Display B:
A value corresponding to input 0% will be output for Output 1 and Output 2.

8.2 Operation
After warm-up status, the unit enters display mode.
The input signal selected in [Input type] will be converted to the output selected in
[Output 1 type] and [Output 2 type].

8.2.1 Input Indication Range

The measured value is indicated within the following range:
[Output 0% value – (Output 100% value – Output 0% value) ×10%] to
[Output 100% value + (Output 100% value – Output 0% value) ×10%]
For a value lower than (and including) -2000, the input value and the minus (-) sign
will be indicated alternately. For a value higher than (and including) 10000, the lower
4 digits will flash. (The placement of the decimal point follows the selection.)
If the measured value exceeds the indication range: will flash.
If the measured value drops below the indication range: will flash.
8.2.2 Indication Range of Output 1 and Output 2
The output value is indicated within the following range:
[Indication value at output 0% – (Indication value at output 100% – Indication
value at output 0%) ×10%] to
[Indication value at output 100% + (Indication value at output 100% – Indication
value at output 0%) ×10%]
However, the high limit value is 9999, and the low limit value is -1999. (The placement
of the decimal point follows the selection.)
8.2.3 Input Disconnection
If input is disconnected, the input status will be equal to 0 mA input.
8.2.4 Indication Time Setting
After preset indication time has elapsed, Multi-Display A, Multi-Display B and
each action indicator are turned OFF.
They will light up again if any key is pressed.
They remain lit during setting mode, or in the event of an input error or input
disconnection.
If the indication time is set to 00:00, they will remain lit.
