*However,
Set current (A) x Set current (A) x Load resistance (Ω) x Output time (ms) ≤ 180

[Example]
If the preset current 3.0 A and the resistance 6.0 Ω, then the output current is up to 3.3 ms.

Safety Functions
Safety Functions In a state with the SAFETY plug inserted to the SAFETY connector, trigger signals must not be input.
In addition, the current output terminals are shorted in the DIA-708AS3 so as not to flow the accidental current to the inflator.
Measuring Load Resistence Apply weak current (Approx. 10 mA) to the inflator and measure the resistance.
(*The measured resistance includes the cable resistance to the inflator. )

Measurement range: 0.0 to 10.0 Ω
Resolution: 0.1 Ω
Accuracy: Within ±0.3 Ω

[Resistance measurement before the test]
Just before conducting the test (when moving the SAFETY plug from the SAFETY connector to UNSAFETY connector), automatically measures the load resistance to detect errors such as cable broken.
Only when the measured result is within the preset resistance range, the DIA-708AS3 becomes waiting for trigger state to continue the test.

[Resistance measurement after the test]
After completing the ignition, automatically measures the load resistance for detecting the not ignited inflator.
The measured results are displayed on the status LED on the top face.
CH Status Displays the status of the DIA-708AS3 with the LED on the front panel.
Buzzer The built-in buzzer in DIS-7200AS2 issues alarm in the following incident.
 ・ Recharging the capacitor for current output.
 ・ Detects errors when measuring the resistance.
 ・ Detects errors when checking the current output.
