Checklist after power failure

Check both IGP Controller for the resonators R1 + R2

Current should be below 2 mA (both should show “HV ON” (green LED on)

Check both USV for IGP´S

Check Meerstetter TEC for R1 + R2 + ECDL

Green LED on?

Check in the software TEC Service v2.70 - R1, TEC Service v2.70 - R2 and TEC Service v2.70 - ECDL Baseplate on the ResLab-PC:

How is the behavior of the temperature?

Check both USV for TEC´s

Check the air conditioner for the entire room

Is the air-conditioning system switched on?

Is the V-belt (=Keilriemen) broken?

What is the temperature of the draft (=Zugluft)? → should be >10 °C

Check the electric fuse (=Sicherung) on the third floor

Check the H-Maser

All LED are green?

Check in the Software VCH on the ResLabMobil:

All values except for D2h must be green!

Check the 914nm-laser

Light is on? Powermodule is on?

TA stabilization is ok?

Laserdiode is on?

How much power is in front of the resonator? → should be 70-100 µW

What wavelength does the Wavemeter display?

Check the 10 MHz reference
