Using the Voltage Input Adapter
(Optional)
7-1
7
Use the optional voltage input adapter to record an external 20mV to 1200mV
signal with the temperature pen. When using the Fahrenheit scale chart paper,
values between 2° and 120°F correspond to adaptor inputs of 20mV dc to
1200mV dc. The same correspondence applies to the °F display (2°F = 20mV dc;
20°F = 200mV dc; 120°F = 1200mV dc). While the voltage adapter is in use, the
humidity pen is inoperative and the humidity display is invalid.
Typical applications include monitoring analog output of panel meters, process
signals, and lab equipment. For example, if the adapter is used with a
10mV/degree analog signal, the recorder will display and record 20mV to
1200mV over the range of 2° to 120°F. If the adapter is used with a 1mV/degree
analog signal, the recorder will still display and record 20mV to 1200mV over the
range of 2° to 120°F scale on the chart. However, this plotted range now
corresponds to a range of actual temperatures of 20° to 1200°F.
Polarity of the dc input signal should correspond to the + and – markings on the
adapter.
INPUT VOLTAGES GREATER THAN 20VDC OR 10VAC RMS
MAY DAMAGE THE RECORDER.
Figure 7-1 shows a typical setup using the voltage input adapter.
