Description

The HDS2062M is a handheld battery powered dual channel Digital Sampling Oscilloscope and Multimeter in one. It features a quality colour LCD display, easy-to-use controls and long battery life.
The HDS2062M comes complete with a wide range of useful functions, usualy only available in higher priced alternatives.
Display Modes
Normal - operates like a normal DSO with simple manual control of timebase, triggering etc
XY Mode - With the XY mode selected, CH1 is displayed on the horizontal axis and CH2 is on the vertical axis; when the oscilloscope is under the sampling mode in which no trigger is found, the data appears as light spots.
Auto-set - The Auto-Set feature lets the Oscilloscope display and measure unknown signals automatically. This function optimizes the position, range, timebase and triggering and assures a stable display of virtually any waveform.
Average Display - the displayed waveform is an average of a preset number of waveform samples. This can eleiminate noise which can otherwise obscure readings
Persistence mode - in this mode, the screen is not cleared in-between displaying a new waveform sample. Useful for detecting spurious waveform events which would otherwise be missed.
Peak Detection - The oscilloscope takes samples from the maximum and minimum of signals in each sampling interval - used to detect a jamming glitch and reduce the possibity of blurring
Automatic Measurements - The oscilloscope can perform 5 types automatic measurements such as frequency, cycle, average value, peak-to-peak value and root mean square value. And gives two kinds of measurement results simultaneously on the screen.
MATHS functions - shows the result of adding, subtracting, multiplying or dividing calculation on CH1 and CH2 channel waveforms

Waveform Display
Persistence mode
Video Signal Capture
Triggering
There are two triggering modes including Edge triggering and Video triggering.
Edge triggering: The Edge triggering is a mode by which trigger occurs at the triggering threshold value of the input signal edge. With the Edge triggering selected, the trigger happens on the rise or fall edge of the input signal
Video triggering: With Video triggering selected, the oscilloscope performs the NTSC, PAL or SECAM standard video signals field or line trigger
Multimeter
The HDS2062M can also be used in Multimeter mode, and used to make the following measurement;
Direct voltage measurement
Alternating voltage measurement
Direct current measurement
Alternating current measurement Resistance measurement
Diode measurement
Continuity buzzer measurement
Capacitance measurement Other Features
Waveform Storage - up to 4 waveforms can be saved in the HDS2062M's internal memory for comparison display or upload to a PC
Data Upload to a PC - Stored Data can be uploaded to a PC via RS232 or USB in bitmap or ASCII format.

Data Acquisition
The WS10 gets data from the system or process through:
4 built-in signal inputs
RS232 or RS485 serial communication interface
Data acquisition over the RS485 communication interface uses the Modbus RTU protocol. The WS10 acts as a master, polling the Modbus network nodes to get the specified data to its memory. All the data acquired from its local inputs and from external Modbus devices are stored on the WS10 memory. The user can assign identifiers for each memory position. On the configurations of the data access functions, all registers are referenced by their names.
The WS10 can be configured to periodically log data to its Flash memory. This historical logging can then be sent out by e-mail or directly to a computer. With a remote supervision system, this function enables the WS10 to monitor the process and send the acquired data periodically or when the communication link is established.
The instantaneous and historical values acquired from the system or process can be accessed via:
Ethernet interface
RS232, RS485 serial interface or Modem (conventional or mobile).
The WS10 offers five basic applications for remote data access of its data.
Web Browser Access
Modbus TCP or Modbus RTU
Alarm conditions supervision
E-mail transmission
Periodical data transmission
The WS10´s multi-task operating system allows for the simultaneous utilization of all these applications

Web Browser Access
The WS10 can present the acquired data of the process in dynamic user-created HTML pages, that can be visualized by any computer using a Internet browser (Netscape, Internet Explorer, etc). The WS10, connected to the company’s intranet by its Ethernet interface, shares the information (application data) to any computer connected to the intranet, allowing both reading and writing of data, with or without password authorization.
In a remote application, a WS10 connected to a conventional or mobile modem can answer a "dial-up" call connection and present a supervision page to the internet browser of the computer that originated the call, allowing the supervision of remote units.
MODBUS TCP
The WS10 can be configured as a ModbusTCP server and gateway, enabling integration to SCADA supervisory systems. As a server, WS10 accepts connections from multiple SCADA clients, allowing read and write access to its internal registers. This registers are associated to WS10’s local I/O, memory positions or external ModbusRTU devices. As a gateway, WS10 forwards messages between ModbusTCP and ModbusRTU networks, acting as a protocol converter. Both modes may be used simultaneously, while all other WS10 functions remain fully functional. ModbusTCP communication can be used over Ethernet or phone line (fixed or mobile).
Alarm Notification
Tthe WS10 can continuously compare the content of its registers against user programmed limits. The result of this comparison is assigned to a new register that can be used to trigger a local output, write in a remote equipment through the Modbus RTU, send an e-mail or send information to a remote server. The WS10 2 Relays can be activated in response to various alarms
email or Mobile Phone Messages
The WS10 can be configured to send e-mails automatically to an address list. The transmission can be periodical or by exception, based on register values. The e-mails are sent through the Ethernet or Modem and have a dynamic content, sending process data to the recipient. The message sending to cell phones can be done by email (depending on the routing service offered by the mobile phone operator) or directly to a GSM modem connected to the WS10. The e-mail may include, as an attached file, the historical data stored in its memory.
Periodic Data Transmission
The data acquired by the WS10 can be sent periodically to any accessible computer in the Ethernet or Internet (using a conventional or mobile Modem), being received by a TCP server application and stored in a place and format defined by the user. Both instantaneous and historical register values can be sent to the remote server.
Application Topology
Local Operation
Connected to a local network, WS10 can bridge a ModbusRTU network to existing SCADA using Ethernet, expanding data accessibility to virtually all networked computers using internet browser. WS10 can also log historical data, monitor alarm conditions and send e-mail messages in periodical or exception basis. WS10 is an alternative to SCADA in small applications. When the network connection to the internet is properly configured, WS10 data can be accessed from external locations, both by SCADA systems and browsers. The following figure shows WS10 in local application.

Remote Operation
Installed on a remote site, WS10 can connect through a modem to a fixed (optional internal modem) or cellular phone line. Using this connection, WS10 can access internet and send e-mail messages on abnormal conditions or periodically. WS10 can also transfer historical data to a networked computer. Its ability to answer data calls allows dial-up access using SCADA or browser. Remotely installed, WS10 allows additions functionalities when compared to conventional remote units that can only transfer data periodically. The following figure shows WS10 in a remote application.
