OPTIONAL TEMPERATURE/HUMIDITY PROBES
Connection
2.5 mm stereo jack. Functional electrical isolation from PQube.
Location
Optional probes plug into the PQube directly or through PSL-provided extension cable.
Scan Time
5 seconds max.
Temperature Accuracy
Typical: ±0.5ºC. Max: ±2ºC (-20 ~ +80ºC).
Humidity Accuracy
Typical: ±4.5% RH (20 ~ 80% RH), max: ±7.5% (0 ~ 100% RH).
Note: For optimal ambient temperature and humidity accuracy, use extension cable to avoid self-
heating of probe by PQube.

increase the analog input channel ratio by 0.1% (ATT1-0600V) or 0.4% (ATT1-1200V) per meter of cable
to approximately compensate for cable capacitance.
