• Do not subject the Model 250 indicator to shock, excessive vibration or extremes of temperature
(before or after installation).
• Inputs are protected against electrical interference, but excessive levels of electro-magnetic radiation
and RFI may affect the accuracy and stability.
• The indicator should be installed away from any sources of excessive electrical noise.
• The load cell cable is particularly sensitive to electrical noise and should be located well away from
any power or switching circuits.
• For full EMC or for RFI immunity, termination of cable shields and correct grounding of the indicator
is essential.

Use the panel mount template (included with the Model 250 and Model 250SS) for drill hole
locations. The template indicates positions for the two 4mm mounting screws through the panel.
Also displayed on the template is the position of the rectangular hole that should be cut to allow
for the connection of cables. The drilling template supplied with the indicator allows for front or
rear machining of the panel.
