GTC CT8030 Manual

1. SAFE TY RULES
This meter is designed for indoor use at temperatures between 0°C to 40°C and
•
altitudes up to 2,000m.
• To ensure that the meter is used safely, follow all safety and operating instructions in
this operation manual. If the meter is not used as described in this operation manual,
the safety features of this meter might be impaired.
• Do not use the meter if the meter or test leads look damaged ,or if you suspect that
the meter is not operating properly.
• When using the instrument, keep your fi ngers behind the fi nger guards on the plastic
casing and probes.
• Disconnect the live test lead before disconnecting the common test lead.
• Make sure power is off before cutting, desoldering, or breaking the circuit wires. Small
amounts of current can be dangerous.
• Do not apply more than 1000 VDC or 750V AC rms between a terminal and ground.
• To avoid electrical shock, use CAUTION when working above 60V DC or 25V AC rms.
Such voltages pose a shock hazard.
• Never make measurements with the battery cover off.
• To avoid electrical shock or damage to the meter, do not exceed the input limits.
