Operating Instructions
Read Resistance & Check Continuity
Choose this function to measure resistance or check continuity.
Move the power switch
w
to READ then Double Click the EZ-DIAL knob to get
into the Double Click Menu. Turn the knob to scroll through the settings and
press the knob to make your selection. Select OHMS for the FUNCTION, 400Ω,
4000Ω or Continuity for the RANGE.
Disconnect all wires from the sensor and connect the 830PM to the resistor or
sensor using 2, 3 or 4 wires. The 830PM automatically detects how many wires
are connected using a patented circuit and indicates each wire that is connected.
Any wires that are not connected or broken are indicated by the 830PM. This is
useful for troubleshooting the sensor.
If continuity is selected, resistance is measured up to 400.00Ω. The beeper will
sound and )))) appears on the display when resistances < 100.00Ω are measured.
Signals above the maximum scale are limited by protection circuitry with “OVER
RANGE” on the display and the red OVERLOAD LED lit.
The 830PM measures the input signal and constantly updates the display with
the current reading. Move the EZ-CHECK switch
q
to MAX to see the highest
reading and to MIN to see the lowest reading. Press and hold the knob
e
to clear
the MAX and MIN readings.
