Frequently Asked Questions – FAQs

How do I choose a multimeter?

You should buy a multimeter based on these factors

  • Price: The cost of the device or kit
  • Accuracy: how accurate the readings are
  • Working Mode: Manual Range or Auto Ranging
  • Durability and Safety: How durable and how safe it is
  • Features: Which type of readings and under which range they are available

Can a multimeter explode?

Multimeters themselves don’t explode as they are protected with fuses. Multimeters have fuses to protect them against sudden surges and peaks which is beyond the range of the multimeters. Good multimeters use non-exploding fuses which got burned without producing fire and explosion. However, bypassing the fuses or using the wrong fuses can cause the multimeters to catch fire and produce arc flash.

Can you get electrocuted using a multimeter?

If a multimeter is set to read voltages, the internal resistance would be very high and touching a lead (while the other is connected to the circuit) won’t shock you. However, if the multimeter is set to measure current and one lead is connected to the circuit, internal resistance will be nearly zero. Touching the other lead will complete the circuit and it will shock you. However, if no lead is connected to the live circuit, a multimeter can not shock you.

Why does my multimeter read 1?

If a multimeter is showing 1 or OL as an error, this means the multimeter is overloaded. If overloading did not burn the fuse, try to adjust the knob and select the appropriate range.

Which multimeter is more accurate?

Digital multimeters are more accurate than analogue digital multimeters. A true RMS multimeter would be more accurate among the digital multimeters.
