High/Low voltage input selection
1. Gently remove the backplate (it is held in place by four lugs).
. Slide the electronics from the housing.
. Change the High/Low voltage jumper to the required setting (see
diagram right).
. Look inside the housing and note that there are connectors that
mate with the display board.
5. Slide the electronics gently back into the case. Carefully moving the
board until the keypad connectors engage with the display board.

Output calibration
General
The PTX800D analogue outputs are calibrated for a specific output
range and type. If you have changed the output range or type you
must follow the procedure given below.
Allow the instrument 15 minutes of powered operation (to reach a
stable temperature) before calibrating the output.
Equipment requirements
• An accurate digital multimeter (accurate to 0.05 mV and ±0.1 μA)
Terminal Connections for output calibration
