Digital multimeter APPA 97R (APPA Technology Corporation): Brief specifications: DC voltage 300 mV - 1000; The alternating voltage of 3 V - 750 V; DC / AC current of 300 mA, 20 A; 300 Ohm resistance measurement - 30 MW; Withholding evidence; Rang chain; Test pn; BeepGuard; Shock execution; Use in any weather; Extra protection; Color-coded; Reliable switch; Measurement of the rms value of arbitrary waveform True-RMS.
The 90th series multimeters APPA system used BeepGuard ™ - system warnings, and if the expected measurement and the selected mode using the wrong sockets. Superior shock-resistant plastic ensures that even when the unit falling from a height of 1.5 meters the instrument will not fail Developed to work in the harsh conditions of APPA 91, 97 / 97R are equipped with rubber seals at the seams in the rotary switch, connectors probes and the battery cover to protect the unit from dirt, dust and water splashes. Devices are also resistant to shocks and falls. They can be used both in laboratory and field conditions. Each device is equipped with a series of APPA shroud 90 which has a support hole for hanging, and a probe retainer. This housing provides a high degree of safety and ease of use of your device. Input terminals are color-coded marking of the corresponding provisions of the rotary switch. This ensures the correct selection of the input terminal of the corresponding mode you need. The unique rotary switch made from durable plastic with contacts from beryllium-copper and gold-plated contact pads of the circuit board will provide you with many years of trouble-free operation.
