Precautions and preparing for measurements
1. Never apply voltage to the output connectors.
2. Do not use the current clamp for voltages of more than 600V a.c.
3. Make sure the battery is correctly inserted.
4. Only use the adaptor at temperatures from 0 to +50°C and at relative humidifies of less than 75%.
5. Do not store or use the adaptor at high temperatures or high relative humidifies or expose it to direct sunlight.
6. Before changing the battery, switch the adaptor off and unplug the output connectors from the meter.
7. Take the battery out if you are not going to be using the adaptor for any length of time.
8. Switch the adaptor off after use.
(3) Using the adaptor
3.1 Measuring a.c. currents
1. Use the slide switch to set the adaptor to the highest range you will need (600A or 100A).
2. Plug the output connectors (red and black) into the input sockets of a digital multimeter and set the multimeter to
an a.c. voltage range of 200mV or 2V.
