Error Messages
The following hardware errors are indicated by showing the appropriate error number in the display.
The OK key will flash and if pressed the error will be ignored and operation will continue as described.
Error No. Error Description Action on pressing OK
1 Calibration constants corrupted at power-up Loads default calibration parameters
2 # functions corrupted at power-up Loads default # settings

Switching the instrument off with the error message showing will leave all settings unchanged.
Main Outputs – Link Mode (T models only)
In Link mode, selected by pressing the LINK key, the key parameters of the two Main Outputs are
adjusted together; when Link mode has been selected both CONTROLkeys (1 and 2) are lit
to show that both outputs are selected.
The following paragraphs only describe the differences between independent and linked
operation; they should be read in conjunction with the corresponding paragraphs in the Main
Outputs section.
Link Mode Operation
− Overview
Control of the two main outputs can be "linked" so that changes are applied to both outputs
simultaneously. There can be several reasons for wanting to do this:
1. Series or Parallel Wiring
The user may wish to create an output with either twice the voltage or twice the current
capability, see the Series or Parallel Connection with Other Outputs section on page 19.
Link mode provides a convenient means for controlling the two outputs when they are series
or parallel connected.
2. Tracking Voltages (or Currents)
When in Link mode, using Numeric Set will set equal voltages and/or currents on the two
outputs. Control of the outputs can also be linked with different voltages and/or currents set
on the outputs. Use of the Jog control will then make equal changes to the two outputs.
3. Simultaneous Recall of Stored Settings
Each output has its own set of 50 memories. However, when in Link mode, a further set of
50 memories is available which can store settings for both outputs. Voltages and currents
can be set individually for each output and the control put into Link mode before storing. The
stored settings can then be recalled to both outputs simultaneously. Using #98 in Link
mode will clear all the memories of all 3 outputs in all modes, see Extra Functions section.
Notes: The existing settings for Output 1 can be duplicated on Output 2 using the Copy function
before or after linking.
When in Link mode the control functions are limited to Set Range, Set Volts and Set Current
(Numeric Set and Jog set), plus Store and Recall. OVP, OCP and Sense cannot be
changed while in linked mode.
Control of on/off for each output remains separate when in Link mode. To switch the
outputs on or off together the ALL ON/ALL OFF buttons must be used which are
independent of Link mode.
Using #33 in Link mode will lock/unlock front panel control of all 3 outputs simultaneously.
Selecting Link Mode
The only constraint on selecting Link mode is that both Main Outputs must already be set to the
same Range; in particular, the outputs may be linked even if their output voltage and current limit
