Model 34 Temperature Source/Measure |
| The Model 34 Temperature Source/Measure The Model 34 simplifies the testing of temperature sensors by conveniently housing both the Source and Measure in one package. The Model 34 has four distinct capabilities: 1. A COOL Source (either Universal Jaw or "five hole block) with range down to 30°C (22°F) 2. A HEAT Source with range to 500°C (932°F) with Universal Jaw or range to 700°C (1292°F) with a "five hole block." The Model 34 may be ordered with two HEAT Sources and no COOL Source. 3. A Measure for thermocouples, RTDs, and thermistors 4. A Measure for 420mA and 20VDC from temperature transmitters |
ABOVE:
With the HEAT SOURCE at 100.0°C, the thermocouple under test reads 100.8°C on the MEASURE unit, demonstrating a +0.8°C thermocouple error. |

| K, J, T, E, C, S, R,
B, and N thermocouple types may be read with 0.1°C or °F resolution. RTDs (Resistance Temperature Detectors) may be tested in 2-, 3-, or 4-wire modes with alpha values of 0.385 or 0.392. Thermistors (2252 (omega)) are also accommodated. The outputs of temperature transmitters may be read directly by the MEASURE unit in either mA or DC volts. |
