HTC DM-97 Digital Multimeter This model no DM 97 A multimeter or a multitester, also known as a VOM (Volt-Ohm meter or Volt-Ohm-milliammeter ), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter would include basic features such as the ability to measure voltage, current, and resistance. Analog multimeters use a microammeter whose pointer moves over a scale calibrated for all the different measurements that can be made. Digital multimeters (DMM, DVOM) display the measured value in numerals, and may also display a bar of a length proportional to the quantity being measured. Digital multimeters are now far more common but analog multimeters are still preferable in some cases, for example when monitoring a rapidly varying value.

Hall Effect Sensor The RM0435 Sensor is an integrated Hall Effect latched sensor. Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A Hall Effect sensor is much smaller, but can handle less current than a reed switch. Thanks to its wide operating voltage range and extended choice of temperature range, it is quite suitable for use in automotive, industrial and consumer applications. The device is delivered in a Thin Small Outline Transistor (TSOT) for surface mount process and in a Plastic Single in Line (TO-92 flat) for through hole mount. Both 3-lead packages are RoHS compliant. The output signal of this sensor is open-drain type. Such output allows simple connectivity with TTL or CMOS logic by using a pull-up resistor tied between a pull-up voltage and the device output. The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output. An internal band gap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. If a magnetic flux density larger than threshold Bop, DO is turned on (low). The output state is held until a magnetic flux density reversal falls below Burp causing DO to be turned off (high). The RM0435  exhibits latch magnetic switching characteristics. Therefore, it requires both south and north Poles to operate properly.

Remove the connections immediately to restrict the damage to a minimum The instrument can only be used in conjunction with the probe for compliance with safety standards. If the probe needs replacing due to damage, the replacement must be of the same type or the same electrical specifications Do not exceed the input limits specified for each range When the instrument is measuring, do not touch the input terminal, not in use When a measurement range is uncertain, turn the function/range switch to the maximum range position Features: Measurement Capabilities: Measures DC and AC voltage, DC current, resistance, diode, and transistor.
