DG-4240 Measurement Procedure, Method for Releasing Error Messages
The procedure for measurement generally goes as follows.
(1) Connect to peripheral devices.

(2) The power is turned on. This device will immediately enter operational status.
(3) Move the spindle of the gauge sensor to the desired position for the zero point and fix the spindle.
(4) Reset the measurement value to zero using one of the following methods at the zero point position.
• Press the RESET switch on the front panel.
• Short-circuit the RESET input terminal (No. 21) and COM terminal (No. 22) on the rear panel.
• Input a low-level voltage signal from the reset input (pin 32) of the BCD OUT connector on the rear panel.
When the GS sensor spindle is moved, the measurement values are displayed on the front panel, and at the same time, a judgment is made.
- Hold of measurement values
You can hold the measurement values displayed on the front panel and the BCD output. There are two methods for holding.
- Short-circuit the HOLD input terminal (No.20) and the COM terminal (No.22) on the back panel.
- Input a low-level voltage signal from the hold input (pin 31) of the BCD OUT connector on the back panel.
Pass/Fail Judgment / Suspension of Pass/Fail Judgment Output
By inputting the compare gate signal in the following manner, the pass/fail judgment will be forcibly suspended, and all pass/fail output will be turned off.
- Short-circuit the COMPARATOR GATE input terminal (No. 8) and the COM terminal (No. 9) on the back panel.
- Input a low-level voltage from the comparator gate input (pin 34) of the BCD OUT connector on the back panel.
Release of error message
If a miscount occurs in the counting circuit of this device, the display section on the front panel will blink, and the error output (pin 30) of the BCD OUT connector will turn ON. The error state can be cleared using the following zero reset method. Please refer to DG4240 Troubleshooting.
- Press the RESET switch on the front panel.
- Short-circuit the RESET input terminal (No. 21) and the COM terminal (No. 22) on the back panel.
- Input a low-level voltage signal from the reset input (pin 32) of the BCD OUT connector on the back panel.
