x
When the message display shows “4 mA,” the output current must be within in the range
shown in Table 1.
x
Press the [ENT] key repeatedly until the message displays shows “12 mA.” When it shows
“12 mA,” the output current must be within the range shown in Table 1.
To skip the current output not needed to be checked, just press the [ENT] key.
x
Press the [ENT] key repeatedly until the message displays shows “20 mA.” When it shows
“20 mA,” the output current must be within the range shown in Table 1.
x
From the above last step, proceed directly to the temperature indication check in Item 3.3.

From the last step in Item 3.3, Current Output Test, press the [ENT] key repeatedly until the
message display shows “PT1000.”
x
Change the resistance value of the resistance box 1 (for temperature) as shown in Table 2-1
and check the temperature readings. Each temperature reading must be within the range.

From the last step in Item 3.4, Temperature Indication Check, press the [ENT] key
repeatedly until the message display shows “SEL.10.”
x
Press the [ENT] key. The message display shows “

” momentarily, followed by
“RES.1.”
x
Set resistance box 2 to the value shown in Table 3 and check the indication. The resistance
indication must be within the range.
