Short all 4 test clips together, spacing the HS and LS clips the same distance apart as the leads on the DUT. The HD and LD clips should be placed to the outside of the HS and LS clips. Press the Zero/Range key and the LCD will again display ‘Open Short Exit’ on the second line. Press the key under ‘Short’ and the instrument will measure the residual impedance and zero the meter for 0 ohms resistance at the selected frequency. The correctable range is 50 maximum for the absolute impedance and 20 for the resistance. An error message will be displayed if the impedance doesn’t fit into these characteristics. One possible cause for an error is poor contact between the test clips and the DUT. Try to clean the clips and the leads and perform another zero correction. Remove the short from the 4 test clips. The meter is now ready to perform measurements
