Qrae ii user manual

Our high quality field supplies, including NIST traceable calibration solutions and gases, come at significant savings over manufacturer brands.

Now lighter, smaller, more accurate, and with an improved user interface, the only instrument you need to take into the field just got even better. Advanced and durable, the Levelogger Edge is the latest water level datalogger from Solinst. An all new sensor design manages to achieve excellent accuracy while being more robust then previous models and remaining economical.

The MultiRAE Series of handheld gas detectors includes three models for detection of up to six threats simultaneously. Choose from 25 toxic sensors, 3 PID sensors with a 9. Table Of Contents. Quick Links. Table of Contents. Previous Page. Next Page.

All newly purchased RAE Systems instruments should be bump tested by exposing the sensor s to known concentrations of calibration gas. Page 8: General Information 9 oz g diffusion model, 12 oz g , pump version, handheld size.

This long-life battery keeps settings in memory from being lost whenever the Li-ion battery or alkaline batteries are removed.

If conditioning is required, it can take anywhere from seconds to several minutes. Page 14 1. This means that the monitor will run a second cycle of conditioning. Note: The time necessary for conditioning depends on how long the monitor has been without power. Page Inverting The Display Icons, page When the image inverts, release the key. Unit off Caution: The alarm is very loud. During shutdown, you can mute most of the sound by holding a finger over the alarm port.

Page Normal Mode Programming Mode for information on entering the other two modes. Page Diagnostic Mode Run time. Date, Time, and Temperature. The full date of month, day, and year, as well as the hour time in hours, minutes, and seconds, is shown. Two sensor options are available. When any sensor is exchanged for another type, the firmware must be set to match the sensor. The upper right sensor slot can accommodate a CO sensor. The upper left sensor slot accommodates an H S 0.

In Programming Mode, set the pump to operate at High speed. Page Adjust Pump Stall: Low 1. In Programming Mode, set the pump to operate at Low speed. Write down the maximum reading. This is your unblocked reading. Block the inlet for 3 seconds. Note: If the increase is less than 10 counts, there is a leak in the gas inlet or the pump is weak. The submenus and actions are shown in the following diagram.

Page 30 Multiple Sensor Calibration. This function simultaneously determines the second point of the calibration curve for multiple sensors in the monitor.

Single Sensor Calibration. This procedure determines the second point of the sensor calibration curve for a single sensor. In addition, the QRAE II alarms if one of the following conditions occurs: battery voltage falls below a preset voltage level 3. Page 33 Quit without saving settings. Note: This function does not include LEL or oxygen sensors. You can clear all data from the datalog.

The display shows: Are you sure? Select Memory Full Type. Once the datalog is full, it can either stop retaining all data to that point or wrap around, meaning that it begins overwriting the earliest data and proceeding to replace old data in an ongoing manner.

Your choices are Auto Reset and Latched. A latched alarm stays in alarm until you acknowledge the alarm by pressing a button. An auto-reset alarm turns off when the condition that set off the alarm is no longer present for instance, a high H2S reading that exceeds the preset threshold and triggers an alarm, but then lowers below that threshold, turning the alarm off.

Page 41 2. Press [MODE] to save your choice and to exit to the next menu item. Change Startup Mode. Options are Normal Startup and Fast Startup. Fast Startup skips showing you many settings and is best suited to environments where the QRAE II is turned on and off very often during a given day. Options are Pump Mode and Diffusion Mode. When a sensor is disabled, the unit does not datalog or display gas concentrations of that type.

Page 46 4. This sets an optional step after the QRAE II starts up, pausing to ask whether you want to perform a zero fresh air calibration. To calibrate, turn the gas flow on. Page Zero Fresh Air Calibration 3. Page Multiple Sensor Calibration 3. Page Single Sensor Calibration 3.
