Below is the auditor's findings.
Based on the calibration of sealing bar for packing machines, sighted deviation more than ±2° 1) Machine Sanko 2 (Horizontal)
Set = 200 Actual = 199.9 Indicated = 198 Correction = -2.1 2) Machine SN1 (vertical)
Set = 149 Actual = 139.9 Indicated = 142 Correction = +2.1 3) Machine Sanko 4 (Vertical)
Set = 200 Actual = 199.9 Indicated = 198 Correction = -2.1
The problems is the temperature is my CCP 3. How am i gonna answer to this findings? My critical limits for this CCP 3 are 140 ◦C to 200 ◦C.
Please advise me.
I assume the value designated "actual" temperature is that indicated by a reference instrument.
I assume the value designated "indicated" temperature is that shown by the temperature thermocouple in the machine.
I assume the data is for 3 different units whose temperature gauges are stated to have a maximum tolerance of +/- 2.0degC.
If as above, seems to me the data indicates that at the quoted temp. reference points, machines 1-3 require correction factors of +1.9, -2.1, +1.9 degC respectively (cf. yr values of -2.1,+2.1,-2.1)degC
Regardless, if the problem is that the allowed tolerance is max. +/- 2.0degC, my interpretation indicates a problem for temperature gauge in machine 2 such that 2 options are normally available, ie -
(1) adjust the zero on the machine temperature gauge.
(2) if (1) not possible then replace the temperature gauge.
Perhaps i have misunderstood yr problem. If so, please clarify.
