Martel Electronics 3001 - Manual (Page 18)

3. Getting Started
After unpacking the 3001 and becoming familiar with the layout and general operation of
the unit as described in the previous section, it is ready to set up for operation.
The following steps should be followed to set up the 3001 for operation:
a) Before attaching the power cord to the rear connector, check that the line voltage
selector is set appropriately for your location. The 3001 is shipped from the factory
with the line voltage set for the country of purchase. To verify the line voltage setting,
check the indicator on the power line voltage selector and fuse compartment cover;
see figure 5 in section 2.5 for the location.
Confirm that the setting is correct according to the following guidelines:
Line Voltage (50/60Hz) Selector Position
90 to 135 VAC 120 VAC position
220 to 250 VAC 240 VAC position
If the setting is not correct, follow the instructions in section 11.3 to change it.
b) Once the voltage selection has been made, making sure that the power switch is off,
connect the AC power cord to the 3001; see figure 5 in section 2.5 for the location.
c) Turn on the 3001 using the rear panel mounted rocker switch. The 3001 should
power up within a few seconds, briefly displaying the model number and firmware
version in the primary display before reverting to the normal input/output display.
NOTE: If a proper power up display does not occur within 30 seconds, turn the power
off, wait a few seconds, and repower the unit. If the problem persists, report the problem
to Martel immediately.
Warm up time is twice the time since last warmed up, to a maximum of 30 minutes. For
good stability it is best to leave the 3001 on all the time.
4. Primary Inputs and Outputs
4.1 DC Voltage Output
The 3001 can source DC voltages from 0 V to 100 V, using the following four ranges for
maximum accuracy: .1 V, 1 V, 10 V, and 100 V.
a) Disconnect any test leads from external devices.
b) Press the key to select DC voltage and current mode, if not already selected.
If DC current mode is displayed, press the key again to cycle to DC voltage mode.
c) Connect the unit under test to the voltage output terminals of the 3001 as shown in
figure 10.
