Page 8: Cautions
Always remove the test leads before replacing the battery or fuses. Inspect the condition of the test leads and the meter itself for any damage before operating the meter. Use great care when making measurements if the voltages are greater than 25VAC rms or 35VDC. These voltages are considered a shock hazard. Warning! This is a class A equipment. This equipment can cause interference in residential areas; in these cases the operator may be required to take steps to avoid or minimize the interference. Always discharge capacitors and remove power from the device under test before performing Diode, Resistance, or Continuity tests. Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty of connection to the recessed electrical contacts. Other means should be used to ensure that the terminals are not "live". If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. This device is not a toy and must not reach children’s hands. It contains hazardous objects as well as small parts that the children could swallow. Do not leave batteries and packing material unattended; they can be dangerous in the hands of children. In the event that the device is going to be unused for an extended period of time, remove the batteries. Expired or damaged batteries can cause cauterization on contact with the skin. Always, therefore, use suitable gloves in such cases. Ensure that the batteries are not short‐circuited. Never incinerate batteries. GX900-GX930-EN V1.1 5/14 ... -

USE EXTREME CAUTION when working with high voltages. 3. DO NOT measure voltage if the voltage on the "COM" input jack exceeds 1000V above earth ground. 4. NEVER connect the meter leads across a voltage source while the function switch is in the current, resistance, or diode mode. Doing so can damage the meter. 5. ALWAYS discharge filter capacitors in power supplies and disconnect the power when making resistance or diode tests. 6. ALWAYS turn off the power and disconnect the test leads before opening the covers to replace the fuse or batteries. 7. NEVER operate the meter unless the back cover and the battery and fuse covers are in place and fastened securely. 8. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. GX900-GX930-EN V1.1 5/14 ... -
