3.5 Temperature Indication Check
Following Section 3.4, press the [ENT] key until the message display shows “PT1000.” In
this state, change the resistance of the decade resistance box 1 and check the data
display. The value on the data display must be within the range shown in Table 3.

3.6 Resistance Indication Check
Following Section 3.5, press the [ENT] key until the message display shows “RES 1.”
Each time the [ENT] key is pressed, the message display changes : “RES 1”  “RES 2”
 “RES 3” ……  “RES 12.” When the message display shows the items in Table 4, set
the resistance of the decade resistance box 2 to the corresponding value in Table 4.
Check the data display and the value must be within the range shown in Table 4.
Continue to press the [ENT] key to return to normal measurement mode.
