Frequently Asked Questions

Q1: What electrical parameters does WattorMet Wattmeter measure and display?

WattorMet displays voltage (0–9999V), current (0–16A), wattage (0–3680W), frequency (0–9999Hz), cumulative energy consumption (0–9999 KWh), and real-time running cost — providing a comprehensive set of electrical measurements from a single plug-in device.

Q2: What is the accuracy class of WattorMet and why does it matter?

WattorMet measures to an accuracy class of 0.001, meaning its energy consumption readings are highly precise and reliable — significantly more accurate than basic energy monitors, and suitable for both household energy auditing and professional electrical assessment work.

Q3: Which plug formats is WattorMet available in?

WattorMet is available in EU, US, UK, and AU plug formats, with operating voltages of 230V 50Hz for EU, UK, and AU versions and 120V 60Hz for the US version — covering the major global electrical standards without requiring adapters.

Q4: What is the maximum current WattorMet can handle?

Maximum current capacity varies by plug format: 16A for the EU plug, 15A for the US plug, 13A for the UK plug, and 10A for the AU plug — covering the standard household appliance range for each respective regional electrical standard.

Q5: How long can WattorMet track cumulative energy consumption?

WattorMet's timing display covers from 0 seconds to 9999 days, and its cumulative KWh display tracks from 0.000 to 9999 KWh — supporting continuous long-term monitoring of appliance energy use across months or years without needing to reset.

Q6: Can WattorMet display the actual electricity cost of running an appliance?

Yes. WattorMet allows you to input your local electricity tariff and calculates real-time running cost displayed across a range of 0.00 to 99.99 KWh, converting raw energy consumption figures into the actual monetary cost of operating each appliance.

Q7: Does WattorMet retain its settings and data when unplugged?

No — this is an important note. WattorMet does not include a battery backup, meaning all accumulated data and custom settings are reset when the device is unplugged from the socket or when the power supply is interrupted. Plan monitoring sessions accordingly.

Q8: Is WattorMet suitable for DIY home energy auditing?

Absolutely. WattorMet's plug-and-read operation, comprehensive multi-parameter display, and cost calculation features make it one of the most practical and informative wattmeters available for DIY enthusiasts wanting to identify energy-hungry appliances and reduce household electricity costs.
