MAKING MEASUREMENT
4.1 Making Measurement: -
Note:
For unknown resistances (Devices Under Test) always start with a higher range selection.
Ensure warm up of the Instrument for the specified time.
• Select PULSE / CONT mode as per requirement.
• Select Ω / mΩ mod.
• Select the appropriate range by pressing one of the 2mΩ to 2000Ω range switches.
Note
Pulse mode operation does not require Zeroing of the instrument and if done gives erroneous
readings.
• Ensure Zeroing of the instrument (for CONT. mode only).
Caution
Always turn OFF the power from the resistance under test. Do not connect the current or
voltage leads of the instrument to any line circuit since this may result in damage to the
instrument and void the warranty.
• Make the connections to the Device Under Test (Refer Fig. No. 4.1) by using appropriate
test leads (refer section 1.5)
• Observe the display, if it blinks in the CONT mode or blank in the PULSE mode, then
select the next higher range.
• The Display will update continuously during CONT mode and will be latched in the
PULSE mode.
