• the LDO sensor cap should be replaced • the calibration is out of range • the calibration results are outside acceptance criteria settings About sample measurements Each probe has specific preparation steps and procedures for taking sample measurements. For step-by-step instructions, refer to the documents that are included with the probe. About check standards Run Check Standards verifies equipment accuracy by measuring a solution of a known value.
View stored data Print stored data The data log contains sample, calibration and check standard data. The most recent data point in the data log is tagged as Data Point 001. The meter must connect to AC power to start the USB connection. Make sure that the connection to AC power is made before the meter is powered on. All data can be sent to a printer. The PD-24 Citizen Printer is compatible with the HQd meters and is FCC Part 15B, Class B compliant with the HQ meters.

Refer to Examples of printed reports on page 28 for further information. key. Select Report Options. 1. Push the 2. Select Report Type and select one of the options. Option Description Basic report One line of data. Advanced report Two lines of data. The first line contains the same information as in the basic report. Total report Three lines of data.
Open data files on a PC Data that has been downloaded to a USB storage device can be transferred to a computer. The data is sent in a text (.txt) file format. 1. Plug the USB storage device into the computer. 2. Find the data file. The file will have the following format: “Meter Serial Number-Data File Type-Date Time”. Example: 9999NN000000SENDDATA-0603131624.TXT 3. Save the data file to a location on the computer. 4. Open a spreadsheet program such as Microsoft® Excel® spreadsheet software. 5.

Remove column headers Advanced operation When transferred data is viewed in a spreadsheet program, the first row of data contains headings to identify the type of data in each column. If an application or post-processing method is used that is incompatible with the headers, the column headers can be omitted. Security options 1. Push the key. 2. Select Column Headers. 3. Set the column headers to off.
1. Push the key and select Security Options. 2. Change the settings as needed to allow or prevent menu access. Option Description Security Options When Security Options is on, and a password has been specified, the password is required to enable the Full Access Options menu. If the meter is turned off while Security Options is on, the password is required to enable the Full Access Options menu again when the meter is turned on.
Table 3 Operator access options Option Description (Probe model) settings Only methods (if methods exist) can be selected. Refer to the probe documentation. Option Description Autoshutoff To maximize battery life, set a time period after which the meter will automatically power off if no key is pushed (1, 2, 5, 10, 30 min, 1 h, 2 h or never). Auto-shutoff is not active when the meter is connected to AC power or in the Interval Reading Mode.
