(3) Zero remaining resistance modes in table 6. Use table 6 to configure the TI for
the resistance mode to be zeroed. Ensure that FAST remains de-selected for all
measurements.
WARNING
The TI can deliver a lethal electrical shock when operating in
the High Voltage Resistance mode (Ω PLUS HiVΩ). Voltages
up to 240 V may be present on the terminals. When connecting
or disconnecting resistors, select Ω, (disabling Ω PLUS Hi VΩ)
to remove high voltage from the terminals. Re-select Ω PLUS
measurements.

(4) Ensure that Ω pushbutton has been selected to remove HI Voltage from TI
terminals (see warning above).
(5) Populate table 7 with the test report values of the standard resistors (transfer
(6) Connect equipment as shown in figure 4 using the first resistance standard and
TI range in table 7. Use table 6 to configure the TI in the 4-wire normal Ω mode.
