SAFETY INSTRUCTIONS
This meter has been designed for safe use, but must be operated with caution. The rules listed below must be carefully followed for safe operation.
1.NEVER apply voltage or current to the meter that exceeds the specified maximum:
|
Input Limits |
Function |
Maximum Input |
VAC |
600V DC/AC |
V DC or V AC |
600V DC/AC, 200Vrms on 200mV range |
mA DC |
200mA 250V fast acting fuse |
A DC |
10A 250V fast acting fuse(30 seconds max |
|
every 15 minutes) |
Resistance, Continuity |
250Vrms for 15sec max |
2.USE EXTREME CAUTION when working with high voltages.
3.DO NOT measure voltage if the voltage on the "COM" input jack exceeds 500V above earth ground.
4.NEVER connect the meter leads across a voltage source while the function switch is in the current, resistance, or diode mode. Doing so can damage the meter.
5.ALWAYS discharge filter capacitors in power supplies and disconnect the power when making resistance or diode tests.
6.ALWAYS turn off the power and disconnect the test leads before opening the doors to replace the fuse or batteries.
7.NEVER operate the meter unless the back cover and the battery and fuse doors are in place and fastened securely.

SAFETY SYMBOLS
WARNING
This symbol adjacent to another symbol, terminal or operating device indicates that the operator must refer to an explanation in the Operating Instructions to avoid personal injury or damage to the meter.
This WARNING symbol indicates a potentially hazardous situation, which if not avoided, could result in death or serious injury.
CAUTION
MAX 500V
This CAUTION symbol indicates a potentially hazardous situation, which if not avoided, may result damage to the product.
This symbol advises the user that the terminal(s) so marked must not be connected to a circuit point at which the voltage with respect to earth ground exceeds (in this case) 500 VAC or VDC.
This symbol adjacent to one or more terminals identifies them as being associated with ranges that may, in normal use, be subjected to particularly hazardous voltages. For maximum safety, the meter and its test leads should not be handled when these terminals are energized.
This symbol indicates that a device is protected throughout by double insulation or reinforced insulation.

NOTE: Accuracy specifications consist of two elements:
!(% reading) – This is the accuracy of the measurement circuit.
!(+ digits) – This is the accuracy of the analog to digital converter.
NOTE: Accuracy is stated at 65oF to 83oF (18oC to 28oC) and less than 75% RH.
