手持气象仪使用方法
嘿，咱聊聊手持气象仪使用方法呗。

这手持气象仪啊，用起来还挺方便的呢。

首先呢，拿到手持气象仪，先看看说明书呗。

了解一下各个按钮是干啥的，别瞎按一通。

就像你买了个新手机，总得先看看说明书，知道咋用吧。

然后呢，打开气象仪。

一般都有个开关按钮，按一下就开了。

屏幕上会显示各种数据，比如温度、湿度、气压啥的。

这时候你可以拿着气象仪到处走走，看看不同地方的气象情况。

接着，如果你想测量风向，那就得把气象仪举起来，让它对着风的方向。

它上面可能有个小箭头啥的，指示风向。

你可以站在不同的位置，感受一下风是从哪个方向吹来的。

就像你放风筝的时候，得看看风向，好让风筝飞得更高。

还有啊，如果你想测量降雨量，那可能得等下雨的时候。

有些手持气象仪有个小杯子啥的，可以收集雨水，然后测量降雨量。

不过这得等下雨，有点靠运气哦。

要是你想知道什么时候日出日落，有些气象仪也能显示呢。

你可以设置一下地点啥的，它就能告诉你当地的日出日落时间。

就像你计划去看日出，得先知道啥时候太阳出来吧。

举个例子哈，我有个朋友喜欢户外运动，他就买了个手持气象仪。

有一次他去爬山，带着气象仪。

一路上他可以随时看看温度、湿度，还能知道风向。

他说这可太方便了，能让他更好地准备装备，也能让他更安全地爬山。

所以啊，手持气象仪使用方法不难，只要多试试，就能用好它。

LayoutThe following figure shows the layout of the GT-324 and provides a description of the components.Figure 3 – GT-324 Layout2.3. Default SettingsThe GT-324 comes with the user settings configured as follows.2.4. Initial OperationThe battery should be charged for 2.5 hours prior to use. Refer to Section 7.1 of this manual for battery charging information.Complete the following steps to verify proper operation.1. Press the Power key for 0.5 seconds or more to turn on power.2. Observe the Startup screen for 3 seconds then the Sample screen (Section 4.2)3. Press Start / Stop key. The GT-324 will sample for 1 minute and stop.4. Observe the counts on the display5. Rotate the Select dial to view other sizes6. The unit is ready for use3. User InterfaceThe GT-324 user interface is composed of a rotary dial, 2 button keypad and an LCD display. The keypad and rotary dial are described in the following table.4. OperationThe following sections cover the basic operation of GT-324.4.1. Power UpPress the Power key to power up the GT-324. The first screen shown is the Startup Screen (Figure 4). The Startup Screen displays the product type and company website for approximately 3 seconds before loading the Sample Screen.4.1.1. Auto Power OffThe GT-324 will power down after 5 minutes to preserve battery power providing the unit is stopped (not counting) and there is no keyboard activity or serial communications.4.2. Sample ScreenThe Sample Screen displays sizes, counts, count units, and time remaining. The time remaining is displayed during sample events. The Sample Screen is shown in Figure 5 below.Channel 1 (0.3 ) is displayed on Sample Screen Line 1. Rotate the Select dial todisplay channels 2-4, battery status, ambient temperature, and relative humidity on line 2 (Figure 6).4.2.1. Warnings / ErrorsThe GT-324 has internal diagnostics to monitor critical functions such as low battery, system noise and an optical engine failure. Warnings / errors are displayed on Sample Screen Line 2. When this occurs, simply rotate the Select dial to view any size on the top line.A low battery warning occurs when there is approximately 15 minutes of sampling remaining before the unit stops sampling. A low battery condition is shown in Figure 7 below.Excessive system noise can result in false counts and reduced accuracy. The GT-324 automatically monitors system noise and displays a warning when the noise level is high. The primary cause of this condition is contamination in the optical engine. Figure 7 shows the Sample screen with a System Noise warning.Count Units (Section 4.3.3)Time RemainingA sensor error is reported when the GT-324 detects a failure in the optical sensor. Figure 9 shows a sensor error.4.3. SamplingThe following sub-sections cover sample related functions.4.3.1. Starting/StoppingPress the START/STOP key to start or stop a sample from the Sample Screen. Depending on the sample mode, the unit will either run a single sample or continuous samples. Sample modes are discussed in Section 4.3.2.4.3.2. Sample ModeThe sample mode controls single or continuous sampling. The Manual setting configures the unit for a single sample. The Continuous setting configures the unit for nonstop sampling.4.3.3. Count UnitsThe GT-324 supports total counts (TC), particles per cubic foot (CF), particles per cubic meter (M3) and particles per liter (/L). Concentration values (CF, /L, M3) are time dependent. These values may fluctuate early in the sample; however, after several seconds the measurement will stabilize. Longer samples (e.g. 60 seconds) will improve concentration measurement accuracy.4.3.4. Sample TimeSample time determines the sample duration. Sample time is user settable from 3 to 60 seconds and is discussed in Sample Timing below.4.3.5. Hold TimeThe hold time is used when Samples is set for more than one sample. The hold time represents the time from the completion of the last sample to the start of the next sample. The hold time is user settable from 0 – 9999 seconds.4.3.6. Sample TimingThe following figures depict the sample timing sequence for both manual and continuous sampling. Figure 10 shows the timing for manual sample mode. Figure 11 shows the timing for continuous sample mode.

MaintenanceWARNING:There are no user serviceable components inside this instrument. The covers on this instrument should not be removed or opened for servicing, calibration or any other purpose except by a factory-authorized person. To do so may result in exposure to invisible laser radiation that can cause eye injury.7.1. Charging the BatteryTo charge the battery, connect the battery charger module AC power cord to an AC power outlet and the battery charger DC plug to the socket on the side of the GT-324. The universal battery charger will work with power line voltages of 100 to 240 volts, at 50/60 Hz. The battery charger LED indicator will be Red when charging and Green when fully charged. A discharged battery pack will take approximately 2.5 hours to fully charge.There is no need to disconnect the charger between charging cycles because the charger enters a maintenance mode (trickle charge) when the battery is fully charged.7.2. Service ScheduleAlthough there are no customer serviceable components, there are service items which ensure the proper operation of the instrument. Table 1 shows the recommended service schedule for the GT-324.7.2.1. Flow Rate TestThe sample flow rate is factory set to 0.1cfm (2.83 lpm). Continued use can cause minor changes in flow which can reduce measurement accuracy. A flow calibration kit is available separately that includes everything needed to test and adjust the flow rate. To test the flow rate: remove the Isokinetic inlet. Attach the tubing connected to the flow meter (MOI# 9801) to the instrument inlet. Start a sample, and note the flow meter reading. The flow rate should be 0.10 CFM (2.83 LPM) 5%.If the flow is not within this tolerance, it can be adjusted by a trim pot located in an access hole in the side of the unit. Turn the adjustment pot clockwise to increase the flow and counter-clockwise to decrease the flow.7.2.1. Zero Count TestAir leaks or debris in the particle sensor can cause false counts which may result in significant count errors when sampling in clean environments. Perform the following zero count test weekly to ensure proper operation:1. Attach zero count filter to the inlet nozzle (PN G3111).2. Configure the unit as follows: Samples = MANUAL, Sample Time = 60 seconds,Volume = Total Count (TC)3. Start and complete a sample.4. The smallest particle size should have a count <= 1.desired.7.2.2. Annual CalibrationThe GT-324 should be sent back to Met One Instruments yearly for calibration and inspection. Particle counter calibration requires specialized equipment and training. The Met One Instruments calibration facility uses industry accepted methods such as ISO.In addition to calibration, the annual calibration includes the following preventative maintenance items to reduce unexpected failures:∙Inspect filter∙Inspect / clean optical sensor∙Inspect pump and tubing∙Cycle and test the battery∙Verify RH and Temperature measurements7.3. Flash UpgradeFirmware can be field upgraded via the USB port. Binary files and the flash program must be provided by Met One Instruments.8. TroubleshootingWARNING:There are no user serviceable components inside this instrument. The covers on this instrument should not be removed or opened for servicing, calibration or any other purpose except by a factory-authorized person. To do so may result in exposure to invisible laser radiation that can eye injury.The following table covers some common failure symptoms, causes and solutions.9.
