  If your BIRD Measuring Instruments power meter has no power, check the following: * Ensure the batteries are charged; if not, recharge them. * Verify the AC power cord is connected. * Make sure the ON/OFF rocker switch on the rear panel is set to ON. * If using a Cal Cart, confirm its AC power cord is connected. * Check the fuse rating and replace the fuse if it is blown.

Why is the IEEE-488 Interface on my BIRD Measuring Instruments not responding?
- J
  Jackie PetersenAug 16, 2025
  If the IEEE-488 Interface of your BIRD Measuring Instruments does not respond, verify that the address in the interface program matches the address setting on the DIP switches of the interface module. If they don't match, change either the program or the DIP switch setting to ensure they are the same. Check if the power meter fails the self-test. If it does, replace the I/O hub PCB. Also, verify the IEEE cable is not defective and replace it if necessary.
