5 - Calibration (Adjustment)

Warning: Enter the following options only after understanding them completely.
Otherwise, it may be necessary to return the instrument to the factory
for recalibration!
Select ADJUST/CAL option from the SETTINGS > SYSTEM menu. You should
then enter the password 9875 to access the calibration menu.
The password functions as a protection to calibration ranges. After the password
is entered, the menu displays the options GENERAL, INPUTS and PROBE.
Options for INPUTS are mV, mA, ohm and thermocouple.

5.1 - Input Calibration

Select the corresponding mnemonic and apply the signals presented in the tables
below.Note that the applied signals just need to be close to the values shown in the table.
Once the signal has been applied, store the values of the calibration points
1 and 2. Press SAVE to save the typed values

Single range
Input calibration for  is performed in two steps:
a) Application of mV signal:
For the calibration below, leave terminals RTD3 (+) and RTD4 (+) short-circuited .

V_OHM3
V_OHM4
b) Application of standard resistors:
Connect a decade box or standard resistors on terminals RTD1, RTD2, RTD3 and RTD4
(4-wire connection).
