Page 6: Product Specific Safety Information
2. PRODUCT SPECIFIC SAFETY INFORMATION Measurement Category III (CAT III) is applicable to test and measuring equipment connected to the distribution part of the building’s low-voltage MAINS installation. 2.1 Precautions This product has been designed with your safety in mind, but please pay attention to the following warnings and cautions before use. - Page 7 When using test leads, always keep your fingers behind the finger guards on the test lead probes. When this unit is used in combination with test leads, the measurement category of the combination is the lower measurement category of either this unit or the test leads used. Likewise if test lead accessories such as crocodile clips are also used, the measurement category will be the lowest measurement category in that combination.

3. OPERATION 3.1 General If the magnitude of a parameter to be measured is uncertain, but known to be within the maximum safe limits of the electrical tester, manually set the range to maximum. E.g. If measuring AC voltage and the voltage magnitude is unknown, set the range to 600V, then if required select the correct range for a satisfactory reading. -

Page 15: Frequency & Duty Cycle Measurement
Taking all necessary safety precautions, and observing the correct polarity for electrolytic capacitors, connect the test probes to the capacitor to be measured. If the capacitor being measured is charged, diS.C will be displayed on the LCD. Read the measured capacitance from the lower display. 3.19 Frequency &... -
Page 16: Temperature Offset Adjustment
3.21 Temperature Offset Adjustment The offset adjustment allows an individual Type K thermocouple to be optimised for the best measurement accuracy at a chosen reference temperature. The adjustment is accessed by removing the battery cover (see 4.1). Connect the thermocouple to the input socket and place the thermocouple in a known, stable temperature environment at the reference temperature and allow the readings to stabilize. -
Page 17: Diode Testing
3.23 Diode Testing If the diode to be tested is in circuit be sure the circuit power is switched off. Connect the black test lead to the terminal and the red test lead to the terminal. Set the rotary switch to the position. - Page 18 As the source of a live voltage is approached the buzzer will sound intermittently, the red LED will flash and “-” will be displayed on the upper display. Depending on the voltage level, the closer the proximity of the unit to the voltage source, the more rapidly the buzzer sounds and the red LED illuminates, until both become continuous.
