Page 16: Memory Screen
5.6. Memory Screen The GT-526S memory is composed of a single file which contains the data from sample events. Every time a sample is completed, the GT-526S stores that data into the memory. The GT-526S memory is circular, meaning when the memory is full, the unit will start overwriting the oldest saved samples with new samples. -

5.9. Set Flow Screen The GT-526S has a factory calibrated flow rate of 0.1 CFM (2.83 LPM). Use the following procedure to adjust the flow rate when a periodic flow rate check (Section 8.3) indicates a flow rate error greater than +/- 5%. -
Page 18: Set Sizes Screen
Figure 21 – Set Flow Screen 5.10. Set Sizes Screen The GT-526S has six standard factory calibrated particle sizes. These standard sizes will support most applications and provide the best size accuracy (+/- 10%). This unit also supports custom sizes. These sizes are configured using the Set Sizes Screen (Figure 22). -

To charge the battery, connect the battery charger to an AC power outlet and the DC barrel connector to the socket on the right side of the GT-526S. The battery charger is universal and will work with power line voltages of 100 to 240 volts, 50 to 60 Hz. A discharged battery pack will take approximately 2.5 hours to fully charge. -

Page 21: Serial Interface
7.1. Serial Interface The serial interface to the GT-526S is through either the mini-USB or the 9 pin (DB-9) connector. They are located on the right hand side of the instrument as shown below. Communication with the GT-526S through the RS-232 DB-9 port requires a custom serial cable (PN3228). -
Page 22: Commands
7.2. Commands GT-526S provides serial commands for accessing stored data and settings. All commands are terminated by a carriage return. Also, these commands are not case sensitive. The following table lists the available commands. These commands are available via USB, RS232 and RS485 hardware interfaces. The settings (baud rate, parity and stop bits) must match the computer setting for proper communication regardless of the hardware interface type (USB, RS232 or RS485). -

Due to the nature of the instrument, there are no customer serviceable components in the GT-526S. The case of the GT-526S should never be removed or opened for any reason. Opening or removing the case of the GT-526S voids the warranty and may result in exposure to laser radiation, which can cause eye injury. -
Page 25: Flow Rate Test
4. Adjust the flow rate if the error is > ±5% (see section 5.7.1). 8.4. Annual Calibration The GT-526S should be sent back to Met One Instruments yearly for calibration and inspection. The annual calibration cannot be performed by the customer because this calibration requires specialized equipment and a skilled technician. Met One Instruments maintains a calibration facility for calibrating particle counters according to industry accepted methods such as ISO, JIS and NIST. -
