Model 6520 OptionsOverviewandDescription Enhancements for Ultra-high Resistance Measurements Guildline Instruments Limited 6520 Programmable Digital Teraohmmeter is Guildline's latest instrument standard capable of Resistive measurements to 1016 from Guildline Instruments. With wide range of available options, the Teraohmmeter can become truly a Metrologist tool, not just a measurement Instrument. 1 6520 Option Description 65201 PENN AIRBORNE (REFERENCE FIGURE 1) The 65201 Penn Airborne enclosure is to allow the Penn Airborne series of High Value Resistors to be plugged directly in for ease of measurements by the 6520. The connectors are plugged into the front of the 6520. Since the Penn Airborne Resistors were susceptible to variables such as air flow and movement, this option is highly recommended if you calibrate these resistors. Figure 1 - Penn Airborne Fixture 65220 ENVIRONMENTAL MONITOR This option consists of two sensors that plug into the rear of the 6520. One sensor measures temperature and humidity, the second sensor measures barometric pressure. The sensors convert a volt input into a full scale reading. The temperature, humidity and pressure readings can be accessed via the front panel. The readings can also be time stamped. Combined Temperature/Humidity Sensor (Reference Figure 2 and Figure 3) Figure 2 Temperature/Humidity Sensor Construction The RH Sensor construction consists of a planar capacitor with a second polymer layer to protect against dirt, dust, oils and other hazards. The temperature sensors are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The sensor thus has an advantage over linear temperature sensors calibrated in
