OMT-602_ Process Verification Instrument

Product Introduction
OMT-602_ Process Verification Instrument（Handheld signal source）It is a handheld comprehensive digital verification instrument that integrates digital display DC voltage, millivolt, current signal sources, and digital multimeter functions, with high precision, high resolution, high reliability, and anti drop performance. The instrument adopts a large LCD display with a height of 22mm, which provides clear readings. At the same time, the instrument also has an EL backlight source for reading in dimly lit areas; The instrument is powered by AC/DC power, making it more convenient to use. The signal output and milliampere and millivolt measurement functions of this meter are mainly designed for the needs of on-site calibration and maintenance of industrial automation field instruments, with high accuracy. It is an ideal signal source and detection tool for on-site instrument workers, computer distributed control system maintenance personnel, and instrument installation workers.

Functional Description
1. Display: 41/2LCD display, accuracy of 0.05% (0.05%)
2. Power supply mode: The instrument provides a separate 24V power output; Built in rechargeable battery pack (equipped with charger)
3. LCD display, word height 22mm. Over range display shows "1".
4. Output 24V DC power supply, which can be used as a 24V DC working power supply for two-wire instruments.
5. There are DC signal output levels of 0-20V, 0-20mV, 0-20mA, and 0-22mA, which can be used as input or output signals for type II and III instruments. During on-site verification, various type II and III instruments can be simulated.
6. There are measurement modes for 200V, 20V, 200mV, 100mA, and 20mA DC signals, which can be used to measure the working voltage, input and output voltage signals, and current signals of the instrument.
7. The instrument can work simultaneously to output 24V power supply, output DC current signal, and measure functional status.
8. The instrument has a four and a half digit LCD display, and the output value, measurement value, and unit can be selected by rotating the switch.
9. Designed a sealed case according to safety standards and removed the battery cover.
