Connecting the
Recorder Outputs
The Series 1 has two optically isolated recorder outputs. These
outputs provide either a current or voltage signal, which you set using
switch blocks on the channel cards. Although the meter is configured
at the factory, you should check the switch block positions before
making connections. Use the following steps to check or reset these
switch settings:
Accessing the Channel
Cards
1. Remove the screws on the front panel and slide the electronics
unit out of its enclosure.
2. Remove the channel card by pulling the card straight up.
Setting the Switch
Blocks
1. Locate switch blocks S2 and S3 (see Figure 1-2 for switch block
S2 and S3 locations). Switch block S2 controls the output signal
for Recorder A and switch block S3 controls the output signal for
Recorder B.
2. Set the switches in the appropriate positions — I for current or V
for voltage.
3. Check or reset switches for each channel where you are using a
recorder output.
