Specifications (PDF File)

Features:

• AC/DC current: Clamp-on measurement of ac current up to 1400 A rms and dc current up to 2000 A without breaking the circuit

• Highest safety rating: 600 V CAT IV rated for use at the service entrance

• Accurate in noisy environments: Even with distorted waveforms present on electronic loads with low-pass filter

• Data logging: Identify intermittent faults by logging any power parameters for minutes or months, including harmonics

• Verify batteries: Direct measurement of dc ripple (%) for battery and dc systems

• Troubleshoot harmonics: Analyze and log harmonics digitally or graphically

• Inrush current: Capture and analyze nuisance tripping, from 3 seconds to 300 seconds

• Easy to use: Easily confirm instrument setup with large backlit color display of waveforms and trends

• 3-Phase power: Built in capability for balanced loads

• View graphs and generate reports: With included Power Log software

Applications:

• Set up and troubleshoot variable frequency drives and UPS systems - Verify correct operation by measuring key parameters

• Harmonics measurements - Uncover harmonic issues that can damage or disrupt critical equipment

• Inrush capture - Check start-up current where spurious resets or nuisance circuit breaker tripping occurs

• Load studies - Verify electrical system capacity before adding loads

Log measured parameters
All voltage, current, power, and harmonic measurements can be logged for minutes, hours, or months. Measurement averaging periods from 1 second to 15 minutes can be selected depending on the application. Measured parameters can be logged into three separate recording memory areas. If longer recordings are required, the three areas may be combined into one. Stored measurements can be recalled and displayed on-screen in normal screen format or downloaded using the Power Log software package.

Flexible and easy to use
The 345 measures a wide range of electrical parameters and can be used for many applications in today’s modern electrical environment. Measuring mode is selected by a simple turn of the rotary switch and the large color display presents data in a clear, easy-to-understand way. By default the display will show the most common measurements, in very large format. If more detailed views are required they are available with the press of a single key (up to six measurements at once).

Analysis and reporting software
Designed to quickly view recorded data, the included Power Log software displays all recorded parameters on interactive trends. Generate professional reports with the ‘Report Writer’ function, or copy and paste images into report document manually.

• Easy-to-use tabbed window format allows quick data evaluation.

• One-step download and display capability

• Waveform, harmonics, and trend download

• Simple data export to other applications

Inrush current
Diagnose equipment start-ups with the inrush current mode. A current trigger level is set prior to recording. Once the level has been exceeded, the meter will begin capture. Recordings from 3 seconds to 300 seconds may be captured, and up to 1000 inrush events may be stored in the instruments memory.

Screen captures and data logging
Any measurement can be stored in memory for later viewing, or downloaded to a PC. Simply press ‘SAVE’ to capture the active screen to memory – up to 50 screen shots can be saved for quick and simple documentation. Additionally, over 150,000 individual measurements can be logged for later review on the display or on a PC using Power Log software.
