Cautions Do not use the device for a procedure that it is not made for. This can cause damage to the protection. This symbol, adjacent to another symbol or terminal, indicates that the user must refer to the manual for further information. This symbol, adjacent to a terminal, indicates that, under normal use, hazardous voltages may be present. Double insulation. UL listing is not an indication or a verification of the accuracy of the meter 2.
WARNING Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 2.2 Industry Canada Compliance This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: This device complies with Industry Canada license‐exempt RSS standard(s).
3. Introduction Thank you for selecting the FLIR IM75 Insulation MultiMeter. This device is shipped fully tested and calibrated and, with proper use, will provide years of reliable service. 3.

4.2 Function Switch Positions The meter is switched OFF and in full power‐saving mode. OFF The meter can measure voltage (V) through the probe inputs. The meter can measure capacitance, diode polarity or continuity through the probe inputs. The type of measurement is chosen by the MODE button. Earth Bond Resistance testing mode. ZERO Ω 50V, 100V, 250V, 500V, 1KV: Insulation resistance test voltage selections 4.
4.3.1 Selector Pad There are five (5) ‘soft’ function buttons arranged in a square, as shown below. The functions change depending on the sub‐function chosen at the time. Generally the arrow buttons are used for navigation and the TEST‐OK button is used for selecting an object or starting a test. Detailed information below: Fig 4‐3Selector SelectorPad Pad IM75 Pressing the TEST OK button selects a menu‐driven option. The TEST OK button is also used to enter the sub‐menus for selection screens.
CAPACITANCE/DIODE/CONTINUITY: The meter can measure capacitance, diode polarity or continuity through the probe inputs. The type of measurement is chosen by the MODE button. Zero Ω: The meter can measure earth‐bond resistance, through the probe inputs. The measurement unit is Ohms (Ω). 50V: The meter can source a 50VDC TEST Voltage and measure Insulation Resistance through the Zero Ω/Insulation and COM probe inputs.

5. Operation Note: Before operating the device, you must read, understand, and follow all instructions, dangers, warnings, cautions, and notes. Note: When the meter is not in use, the function switch should be set to the OFF position. Note: When connecting the probe leads to the device under test, connect the COM (negative) lead before connecting the positive lead. When removing the probe leads, remove the positive lead before removing the COM (negative) lead. 5.1 Powering the Meter 1.
5.5.2 Auto‐Hold mode If Auto‐Hold mode is switched ON in the settings menu, press the HOLD button to activate Auto‐Hold mode (the ‘H’ display icon will appear flashing). In Auto‐Hold mode readings are captured in the say way as in standard Hold mode. The difference is that the captured reading, displayed on the smaller, secondary display digits, will update whenever a reading 50 units higher or lower than the captured reading is measured. To exit the Auto‐Hold mode press the HOLD button. 5.
5.8 Earth Bond Resistance Measurements (ZERO Ω) 1. Move the function dial to the Earth‐bond resistance position (ZERO Ω); the Earth‐bond resistance icon will appear. 2. Insert the black probe lead into the COM terminal and red probe lead into the ZERO Ohm terminal. 3. Before testing, short the ends of the probes and press the MODE button. The ZERO icon will appear on the display and the offset value will be stored.
5.10 Diode Test Warning: Do not do diode, resistance or continuity tests before you have removed the power from capacitors and other devices under test during a measurement. Injury to persons can occur. 1. 2. 3. 4. Set the function switch to the position. Insert the black probe lead into the COM terminal and red probe lead into the V terminal. Use the MODE button to select the diode test function. The indicator will be displayed.
5.12.2 VFD Mode (ACV only) In VFD (variable‐frequency drive) mode, high‐frequency noise is eliminated from the voltage measurement through the use of a low‐pass filter. VFD mode is available when measuring ACV. 1. Select and then press the TEST OK button to enable the selected (flashing) mode. 5.12.3 Frequency Mode (ACV only) In Frequency mode, the frequency is displayed in the main display and the period is displayed in the secondary display. Frequency mode is available when measuring AC voltage. 1.
5.12.6 Silent Mode In Silent mode, the alert beeper is disabled. Silent mode does not affect the continuity beeper. as described in section 5.12.1 Selecting modes. Select and enable Silent mode 5.12.7 Data Recording Mode (99‐point) The meter has 99 memory locations for the storage of measurement data. as described in section 5.12.1 Selecting modes. Select and enable MEM mode Use the arrow keys to cycle through the mode options: SAVE, LOAD, and CLEAR shown on the secondary display.
6. Maintenance 6.1 Cleaning and Storage Clean the meter with a damp cloth and mild detergent; do not use abrasives or solvents. If the meter is not to be used for an extended period, remove the batteries and store them separately. 6.2 Battery Replacement The Battery symbol flashes with no ‘bars’ when the batteries have reached a critical level of 7.0V. The symbol stays active and visible while the LCD is powered. The meter displays readings within specifications while the low battery indicator is on.
