MB1000 TEST PROGRAM

This executes the MB1000 test program.
1. Preparation
1) Connect the D-sub 15-pin cable to the [METER] terminal on the rear of the DM1000.
2) If there is no DM1000, supply +16.5 V power with an external power supply to the +12V terminal and the ground
terminal.
Note: If a stand-alone inspection is carried out with the unit installed on the DM1000 main unit, the Loopback test
generates an error.

How to start the inspection program

1) While holding down the [PEAK HOLD] switch, the [33-48] switch, and the [MASTER] switch, switch on the power. The
unit goes into stand-alone inspection mode and the switch inspection starts.
2) When you press the [PEAK HOLD] switch, the [33-48] switch, and the [MASTER] switch again, LED Inspection 1
starts. (To inspect the switches again, it is necessary to switch the power off, then on again.)
3) From this point on, pressing the [REMOTE1] switch or the [REMOTE2] switch changes the inspection item.
4) During LED Inspections 6 and 7, pressing the [1-16] switch or the [17-32] switch changes the LED illumination time.
(Each time you press the [1-16] switch, the illumination speeds up; each time you press the [17-32] switch, the illumination
slows down.)
