•Calibration
General
The PTX800A analogue outputs and Inputs are calibrated for a specific
range and type. If you have changed the range or type you must follow
the appropriate procedure.
Allow the instrument 15 minutes of powered operation (to reach a
stable temperature) before calibration.
Note: the procedures below shows calibration for the commonly
used 4-0 mA format. If you have chosen another format, the unit will
prompt you with the high and low values you have selected.
Equipmentrequirements
• An accurate digital multimeter (accurate to 0.05 mV and ±0.1 μA)
• Suitable current/voltage source (accurate to 0.05 mV and ±0.1 μA)
