Lead Compensation Measurement

Lead compensation subtracts the resistance of the test leads from the measured
result.
• Short the two measurement leads connected to H (Z) and E (X) terminals.
• Press the 2nd button, then the START/STOP button to start the measure-
ment.
• This value will be deducted from all resistance values measured thereafter
until the rotary switch is turned to another function.
appears on the display after the compensation value has been measured.
NOTE: If the compensation resistance is > 5Ω, or if the leads are not shorted
when the measurement is started, the value of compensation will be canceled.
