The APM voltmeter and ammeter are the most visible, easy to use, multi-format, programmable panel meter on the market. Providing you with the highest level of accuracy and an immediate visual indication of your critical parameters. The APM has been specifically designed for engineers requiring a more effective way of monitoring and displaying data. The Trumeter APM is a cost-effective alternative to the traditional moving coil and expensive digital panel meters. Trumeter - Revolutionising the future of panel meters
The APM-VOLT digital panel voltmeter boasts a flexible voltage measuring input capable of measuring both AC and DC voltages. It is simple to install and easy to use, automatically detecting AC or DC signals and boasting input ranges of up to 600V.
The APM-AMP digital panel ammeter achieves an accuracy of 1% or better across the input range for precise control where accurate measurement is paramount. It has a direct input for measuring AC and DC currents up to 5A or, in conjunction with a CT, measure AC current up to 1,000A
The APM-FREQ digital panel frequency meter has an input range of 2-400Hz and an impressive accuracy of 0.1%.
APM digital panel meters are suitable for many applications including:
– mains applications – generators and power perfomance monitoring – industrial applications – process monitoring – aviation industry applications
The APM-VOLT meter can measure both AC and DC voltages. The APM-VOLT meter performs automatic AC/DC detection. All AC Voltages are automatically converted to true RMS.
The APM VOLT meter is connected in parallel with the voltage to be measured as shown above
The APM-AMP meter is connected to an external current transformer as shown above. The CT can be placed on either the high side or low side of the load.
In the APM Configurator application make sure that the external sensor is set to ‘CT’ and then enter the primary and secondary currents of the CT that you are using. The APM-AMP meter will then automatically scale its display accordingly
