1. Press and hold down the button (5) using your hand.
2. The test result is indicated by means of indicator lamps (4) and an acoustic signal. See the
following table.
Indicator lamp Result Resistance Acoustic signal
Green GOOD OK 800 kΩ ≤ R ≤ 9 MΩ Yes
Red LOW Not OK R < 800 kΩ No
Red HIGH Not OK R ≥ 9 MΩ No
• If the result is not satisfactory, there may be problems with the wrist strap or the discharge
cable. Conduct suitable tests to troubleshoot.
• Caution! Too low a resistance poses a risk of personal injury.
