- Page 13 • To avoid electrical shock and/or damage to the instrument, do not attempt to take any voltage measurement that might exceed 1000VDC or 750VAC RMS. • To avoid electrical shock and/or damage to the instrument, do not apply more than 1000VDC or 750VAC RMS between the common terminal and the earth ground.
- Page 14 NOTE: • In a circuit, a good diode should produce a forward bias reading of voltage, however, the reverse-bias reading can be variable based on resistance of other pathways between the probe tips. • To avoid electric shock, never measure continuity on circuits of wires with voltage.

NOTE: • The test may take more time for large capacitors to charge, wait until the readings settle before removing the leads. • To improve the accuracy of measurement less than 10nF, subtract the residual capacitance of the meter and test leads. TEMPERATURE MEASUREMENT WARNING: To avoid electrical shock, do not perform temperature measurement when... -
