Selecting Menu

  • When the instrument is turned on, the instrument auto enter DMM Measurement and Source Output mode, the LCD display shown in figure 3.
  • It can measure any circuit or set source parameter to export.
  • Press the button and the LCD display respectively shows MEASURE+SOURCE, MEASURE and SOURCE three menus.
  • Selecting MEASURE in DMM measurement mode, the instrument can measure DMM;
  • Selecting SOURCE indicates source output mode, so the instrument can export source; MEASURE+SOURCE is in DMM measurement and source output mode, the instrument  can measure any circuit and export source at the same time.

Source Output Map:

Volts Output   

As volts source, the maximum output voltage is 15 V.

Current Output

As Source output, the Maximum output Current is 25 mA.

 Frequency Output     

Maximum source output is 5000 Hz in frequency.

  1. Insert the red lead into red output terminal and black lead into black output terminal.
  2. To select volt menu press “M” button, and to select frequency menu press “M” button twice. Volt value is set on the upside of the LCD and frequency value of the Volt is set on the downside of the LCD. The first bit of Volts value is set by pressing the input numeric key to desired value. For example, if we want to set 5V for Volt, then input is “5.0000” on the numeric key. Pressing the “C” button to clear wrong input.

Note: Volts can be set in 5 V, ± 5 V, ± 15 V, 15 V in Frequency output mode.

  1. If we set Volt of frequency above 5 V, the instrument will set 15 V automatically, and if setting Volt value less than 5 V, the Volt will be auto set in 5 V. For ±5 V or ±15 V, first press “+/” button.
  2. Press down key button   , the first bit of frequency setting value is flashing on the downside of the LCD, press numeric key to input desired value of frequency. For example, setting value of output frequency is 60 Hz, then input “60.000” on numeric key. Setting value of Frequency must be standard industry frequency.
  3. Press “confirm” button to confirm the value, the LCD return to display “00.000 V”.
  4. Press the button to export, “60 Hz” and the “OUT” symbol is shown on the LCD. Start the current to export on. To stop the current Output, press the button again, and “OUT” symbol is disappeared.
  5. Set frequency value in the following 18 standard value: 5 kHz, 2500 Hz, 2000 Hz, 1250 Hz, 1000 Hz, 800 Hz, 500 Hz, 400 Hz, 250 Hz, 200 Hz, 160 Hz, 100 Hz, 80 Hz, 60 Hz, 50 Hz, 40 Hz, 25 Hz, 20 Hz. Setting an arbitrary value for frequency not above standard value, then the instrument will auto select a frequency value which your setting value is nearest to standard value.

RS-232 Data Interface

The instrument can transmit data to PC computer by a RS-232 infrared photo electricity interface in real-time mode. Connect the RS-232 interface to a serial port of PC computer, then install the user data record software into the computer according to the README.TEXT file in the SETUP disk. Record and print the measured data of the instrument in real-time mode on the WINDOWS. The user data record special software can complete to record, collate, plot, print data in real-time mode.

Note:  In all measurement mode, the measured data can be transmitted to the PC serial port automatically, but the instrument will stop transmitting in the SETUP mode.

Backlight

The backlight is turn ON when pressing the backlight button. After about 8 seconds, the backlight turn OFF automatically.

Low Voltage Indication 

When the batteries are exhausted and the LCD displays the “9 V” symbol, replace new 9 V alkaline battery; if the LCD displays the “12 V” symbol, replace new 8 piece AA 1.5V batteries.

Note: Exhausted batteries and new batteries can be not used at the same time

Replacing the Fuse

To avoid electrical shock, the instrument must be power off and disconnect the test leads or any input signals before replacing the fuses. Replace only with same type fuses. The input terminal is protected by a 100 mA 250 V fast blow ceramic fuse and 500 mA 250 V fast blow ceramic fuse.

Use the following procedure to replace the blown fuses of the instrument:

  1. Disconnect test leads from the measured circuit, turn off the instrument, and remove the test leads from input jacks.
  2. Unscrew the screw on the back cover, and remove the battery cover.
  3. Remove the blown fuse, replace with the same size and rating fuses.
  4. The input terminal is protected by 100 mA 250 V fast blow ceramic fuse and 500 mA 250 V fast blow ceramic fuse.
  5. Make sure the new fuse is centered in the fuse holder.
  6. Reinstall the batteries cover and the screw.

Replacing the Batteries

To avoid electrical shock, the instrument must be power off and disconnect the test leads or any input signals before replacing the batteries. Never use the instrument unless the back cover of the instrument is fastened completely. Replace only with same type or rating batteries.

When the LCD displays the “9 V” or “12” symbol, the batteries must be replaced to maintain proper operation.

Use the following procedure to replace the batteries:

  • Remove the test leads from tested circuit, turn off the instrument. Remove the test leads from the input jacks.
  • Unscrew the screw on the batteries cover and remove the cover.
  • Remove the exhausted battery and replace with new the same type or rating batteries.
  • Reinstall the battery cover and the screw.

Note: Exhausted batteries and new batteries can be not used at the same time.
