Insert Recorder Output Selection Jumper, Figure 2-2, in position appropriate to the
desired output; 10 mV, 100 mV, 1V or 5V.
On TB2, Figure 2-1, connect leads of shielded recorder cable to "MV+" AND "COM"
terminals.
Connect free end of output cable to appropriate terminals of recorder or other
potentiometric device.
For device with a span of 0 to 10mV, 0 to 100mV, 0 to 1V, or 0 to 5V, connect cable
directly to input terminals of the device, making sure polarity is correct.
For device with intermediate span, i.e., between the specified values, connect cable to
device via a suitable external voltage divider, as shown in Figure 2-3.
