Factory Channel settings:
To obtain factory preset values simply re-apply power with ^v key pressed in. Factory settings are as follows:
MODEL NO. MODEL NO. MODEL NO.
CHANNEL NOS. DPS3000 Series-P DPS3000 Series-TC DPS3000 Series-TH
CHANNEL 1 Millivolt J T/C Thermistor
CHANNEL 2 Voltage Voltage Voltage
CHANNEL 3 Current Current Current
CHANNEL 4-7 Millivolt J T/C Thermistor
(Channels 5,6 & 7 for DPS3100 & DPS3200 only)
Factory default settings for voltage, current and millivolt are:
CURRENT VOLTAGE. MILLIVOLT T/C
