Installing the Panel
1. Place panel in an empty slot on the rack and attach with mounting
screws (optional).
2. Connect the panel to a power supply.
3. Attach a TPM to one of the available channels on the back of the panel.
4. Label what TPM is attached to which channel in the switch nota-
tion area on the front of the panel.
Note:
User should note each unit’s full scale power and
location in the notation area. Use a water soluble marker to
avoid permanent entries.
5. Repeat steps 3 and 4 for other TPM’s, if necessary.
6. Turn the panel on.
Note:
All TPMs are powered, but only one TPM output is
displayed at a time.
7. Select the desired TPM to be measured by using the channel selector.
Note:
The pots adjust the meter independently of TPM
calibration. The appropriate meter scale (1/2.5/5) must be
used with each TPM.
