General measurement method is as follows.

 

1. Measurement

 

(1) Connects to the peripheral device.

 

(2) Turn on the power. The DG-4240 operates immediately.

(3) Move the gauge sensor spindle to the position where you want to set as a zero point and fixed the spindle.

(4) Reset the measurement value to zero at the zero point using any of the following methods; Press the RESET switch on the front panel.

• Short-circuit between the RESET input terminal (No. 21) and the COM terminal (No. 22) on the rear panel.

• Input a low level voltage signal to the RESET input (Pin 32) of the BCD OUT connector on the rear panel.

(5) Pass-fail decision is implemented at the same time as the measurement value is shown on the display of the front panel when the spindle of the GS sensor is moved.

2. Hold the measurement value

 

It is possible to hold the measurement value shown on the display of the front panel and the BCD output. The following two methods are available;

• Short-circuit between the HOLD input terminal (No.20) and the COM terminal (No. 22) on the rear panel.

• Input a low level voltage signal to the HOLD input (Pin 31) of the BCD OUT connector on the rear panel.

3. Stop the pass-fail decision output

 

When the COMPARATOR GATE signal is input in the following method, the pass-fail decision is forcedly stopped and all decision result output turned OFF.

 

• Short-circuit between the COMPARATOR GATE input terminal (No. 8) and the COM terminal (No. 9).

• Input a low level voltage signal to the COMPARATOR GATE input (Pin 34) of the BCD out connector on the rear panel.

4. Cancel the error message

 

When miscounting occurs in the counting circuit of the DG-4240, the display on the front panel flashes and the error output (Pin 30) of the BCD OUT connector turns ON. The error can be cancelled with the following method of zero reset.

 

• Press the RESET switch on the front panel.

• Short-circuit between the RESET input terminal (No. 21) and the COM terminal (No. 22) on the rear panel.

• Input a low level voltage signal to the RESET input (Pin 32) of the BCD OUT connector on the rear panel.
