Page 3: Introduction
The maximum ECM current that can be measured by this unit is: r2 ECM: 50 μA. r3 ECM: 100μA (analogue meter limited to 50μA) • The sampling rate for the ECM is as follows: r2: approximately 5Hz r3: 6.25Hz Icefield Instruments Inc. www.icefield.yk.ca 23 January 2019... -
Page 4: Operating Instruction
The keys 2-9 have their letters printed on them (as on a North American telephone keypad). Additional characters are associated with the 1 and 0 keys (punctuation and other letters, respectively) as per the following table: Icefield Instruments Inc. www.icefield.yk.ca 23 January 2019... -
Page 5: Serial Port
These commands perform the following operations: • display clock • set clock • set line frequency rejection mode (r2 only) • configure encoder (r3 only) • clear data storage memory • retrieve data Icefield Instruments Inc. www.icefield.yk.ca 23 January 2019... -

Syncromesh® cable through the encoder and idle pulleys such that the cable is on the other side of the encoder (and the encoder therefore turns in the opposite direction). Icefield Instruments Inc. www.icefield.yk.ca 23 January 2019... - Page 8 For the factory-installed wheel, the value is 57150μm (57.15mm). After entering these values, the stored values will be echoed back to you. Note that the ECM will automatically multiply the pulses-per-revolution value by 4.

Page 9: Running An Ecm Survey
Note that the encoder is always zeroed when a survey is started, so this black reset button does not normally need to be used. Icefield Instruments Inc. www.icefield.yk.ca 23 January 2019... -
Page 10: R3 Wand Wiring
The wiring for the r3 ECM wand is as follows: Function Encoder phase B Encoder phase A Ground Normally-open high voltage button, grounded when pressed. +5VDC encoder supply voltage Normally-open encoder zero button, grounded when pressed.
