The APM provides accurate measurement with an immediate visual indication of critical parameters. It has been designed for engineers who require a more effective way of monitoring and displaying data.** The unique display combines traditional moving coil meters with the latest digital panel meters and it features a multitude of options that can be set using the APM software. The backlight can be programmed to change color to alert the operator when the current or voltage supply is too high or too low, reducing the risk of equipment failing and improving efficiency. **Go to www.trumeter.com/apm for further information** ## **Key Features** ## Unique Display ## Visibility - 40 segment bar graph display - Large 4 digit display - Separate Starburst display area for annunciators, messages and alarm information - Dynamic backlight colour - User adjustable backlight brightness and colour - Large display - Wide viewing angle (both horizontal and vertical) - Custom annunciators - Positive and negative LCD options for indoor or outdoor environments ## Programmable Dimensions: - Scale (offset, gain and linear) and Range (min and max) - User selectable backlight color and intensity - ***NEW*** 20 point non-linearization scaling for non-linear sensors e.g. thermocouples and pressure transducers - ***NEW*** Ten independent alarm set-points - ***NEW*** Configurable digital output delays (control the time output stays open/ closed - .5 seconds – 120 seconds) **MEASUREMENT VOLT AMP FREQUENCY** Input range (DC) 0 - 600V 0 - 5A - Input range (AC) 0 - 600V 0 - 5A 2 - 400Hz Max Using CT 10,000A Accuracy 1% 1% 0.5% Display modes Peak or RMS **ENVIRONMENTAL** Temperature - operating -10 to +60°C Temperature - storage -40 to +70°C IP rating (from the front) NEMA 4 & 12 (UL50) with IP65 **POWER SUPPLY** Nominal Input (AC or DC) 12-24 VAC/VDC **==> picture [236 x 68] intentionally omitted <==** **----- Start of picture text -----**<br> 57mm [2.24”] 53mm [2.09”] 72mm [2.84”]<br>fa fae<br>72mm [2.84”]<br>**----- End of picture text -----**<br> Panel cutout: 68mm x 68mm [2.68” x 2.68”] as per DIN43700/IEC61554 ## **Easy To Use Software** Just plug into any USB port on your PC, run the freely available APM Configurator application and you’re off.
