IDM 98IV & 99IV / EN
 Warning
 Safety Information
Understand and follow operating instructions carefully.
Use the meter only as specified in this manual; otherwise,
the protection provided by the meter may be impaired.
 WARNING
Identifies hazardous conditions and actions that could cause
BODILY HARM or DEATH
 CAUTION
Identifies conditions and actions that could DAMAGE the meter
or equipment under test
 WARNING
˙ When using test leads or probes, keep your fingers behind
the finger guards.
˙ Remove test lead from Meter before opening the battery
door or Meter case.
˙ Use the Meter only as specified in this manual or the protec-
tion by the Meter might be impaired.
˙ Always use proper terminals, switch position, and range for
measurements.
˙ Verify the Meter's operation by measuring a known voltage.
If in doubt, have the Meter serviced.
˙ Do not apply more than the rated voltage, as marked on
Meter, between terminals or between any terminal and
earth ground.
˙ Only replace the blown fuse with the proper rating as
specified in this manual.
˙ Use caution with voltages above 30 Vac rms, 42 Vac peak,
or 60 Vdc. These voltages pose a shock hazard.
˙ To avoid false readings that can lead to electric shock and
injury, replace battery as soon as low battery indicator.
˙ Disconnect circuit power and discharge all high-voltage
capacitors before testing resistance, continuity, diodes, or
capacitance.
˙ Do not use Meter around explosive gas or vapor.
˙ To reduce the risk of fire or electric shock do not expose this
product to rain or moisture.
˙ Wear suitable personal protective equipment when working
around or near hazardous live conductors which could be
accessible.
