2a Channel 1 (CH1) connectors for:
V: volts/mV DC or AC*; Hz: frequency and counts/min,
counts/hour (cpm/cph);
::resistance; RTD: 2-wire,
3-wire (3W), 4-wire (4W) resistance temperature detectors;
: switch operation; mA+, mA-: current. Refer to
Chapter 3 (Electrical and IDOS operations).
2b Channel 1 (CH1) connectors for thermocouples (TC). Refer to
Chapter 3.
2c Isolated channel 2 (CH2) connectors for:
V: volts/mV DC; mA+, mA-: current; 24Vo: 24V loop power
supply; : switch operation; refer to Chapter 3. For HART
connections, refer to Chapter 8.
(COM = Common) Note: * You can measure an AC voltage (maximum: 20 Vrms)
without the GE specified AC probe (P/N IO620-AC). If it is more than
20Vrms, you must use the AC probe (maximum: 300 Vrms) in CH1
connectors V/Hz and COM; see Section 3.2.5.
