Frequently Asked Questions

How do I resolve a slope error during sensor calibration?

• Clean the connected electrode with weak acid solution first. Then check for process coating. Replace the buffer solution if contamination occurs.

Can the analog outputs drive a remote chart recorder directly?

• Yes. The isolated 4-20 mA loops support up to 550 Ohms impedance. This accommodates standard chart recorders and PLC inputs.

What happens if the internal ambient temperature exceeds 60 degrees Celsius?

• The display contrast degrades. Long-term exposure damages internal microelectronics. You must install a sunshield or cooling enclosure.

Is the dual password protection system mandatory for daily operation?

• No. You can leave the password blank for unrestricted menu access. Use the passwords only to prevent unauthorized configuration changes.
