Powering This chapter describes how to operate the A1410 PULSAR using different power supply options. Power indicator The power indicator u is always present in the right top corner of the screen, Figure 0. It shows the level of the battery charge and whether it is being charged. Figure 1: Power indicator The power indicator takes one of the states denoted by the following icons. © 2021 Acoustic Control Systems – ACS Group

Powering Powering To avoid the risk of injuries or equipment damage, use only the USB-AC charger and corresponding USB-Cable delivered with the A1410 PULSAR. To use AC power connect the USB-Cable u to the charger v and the instrument. Plug the charger to the power supply network, Figure 1: Figure 2: Charging over USB-AC charger Using PC USB-plug For charging using PC uconnect the A1410 PULSAR to PC's standard USB-plug, Figure 2: Figure 3: Charging over PC USB-plug If the A1410 PULSAR is off, it indicates charging charging showing screen.

Powering Powering Using Battery Power The A1410 PULSARcomes with a rechargeable lithium-eisenphosphat (LiFePo4) battery with 3000 mA/h. The A1410 PULSAR automatically recharges the battery when you connect the instrument to the AC power. Battery Operating Time The battery operating time depends on the age of the battery and the instrument settings. To provide realistic battery operating times, the A1410 PULSAR has been tested with mid-level operating parameters (repetition rate set to 5 Hz and display brightness set to 75%). The nominal battery operating time for new batteries is about...

Powering Powering Battery Usage Instructions · The battery must reach full charge on a regular basis for proper capacity and cycle-life maintenance. · Fully recharge discharged batteries as soon as possible after use. Storage Instructions · Never store the instrument with discharged batteries. · Store the instrument in a cool, dry environment. · Avoid long-term storage under sunlight or in other excessively hot places such as the trunk of an automobile. · While in storage, fully recharge batteries at least once every two months. Do not open the A1410 PULSAR housing and do not try to...

Getting started Getting started 2 Getting started Powering on Surface preparation Clean the object surface at the transmitter and the receiver locations. It is sufficient to remove dirt, debris and sand. The surface, if possible, should be flat. Measurement · Switch on the instrument by pressing the key. The display shows the welcome screen. Check for the version at the bottom of the screen. If necessary, update the A1410 PULSAR firmware. The A1410 PULSAR loads the parameters from the previous session and starts normally. Switch off the A1410 PULSAR by pressing the key. The A1410 PULSAR...

Getting started Getting started · Save the result by pressing the enter button and the about saving on page Instrument check Instrument check To check the instrument use the plexiglass calibration sample. · Ensure the following parameters are correct (to more information on parameters refer to page 13 ): auto gain = on, measurement scheme = direct, auto zero offset=on,result type = time,mode = digital or waveform. · Perform a measurement according to . Use the grooves at the sample's faces for exact instrument installation. The progress bar shows the end of the measurement process see 23 ....

Getting started Getting started transfer of energy between transducers is at its maximum. Hence the accuracy of velocity determination is therefore governed principally by the accuracy of the path length measurement. Figure 4: Direct scheme Semi-direct scheme The semi-direct scheme (Figure 4) may result in reduction in the accuracy of measurement of the path length. It is generally found to be sufficiently accurate to take this as the distance measured from center to center of the transducer faces. The semi-direct scheme also suffers from reducing of receiver sensitivity. Figure 5:...

Getting started Getting started Indirect scheme Indirect transmission scheme should be used if only one face of the concrete is accessible. It is the least sensitive of the arrangements and it depends on the distance between the transmitter and the receiver. Furthermore, this scheme produces measurements which are usually influenced by the concrete near the surface. Figure 6: Indirect scheme Please confirm, the transmitter and the receiver orientation is correct. User LEMO connectors for visual alignment. © 2021 Acoustic Control Systems – ACS Group

Operating modes Operating modes 3 Operating modes Short description The A1410 PULSAR is operating in following operation modes: setup, digital, waveform, and crack. · In the setup mode, the operator adjusts the measurement settings. Press the key to enter the setup mode. · In the digital mode, the operator reads measured values on a numeric display. The display takes more than half of the screen - this simplifies reading the values at a distance. · In the crack mode the A1410 PULSAR estimates the depth of the crack. Status bar The status bar provides the information about the A1410 PULSAR...
